@AshwinGokhale: I'm not sure what you mean by that sentence?
 
Anonymous
Basically,I am dumb!
 
Huy
Don't say that. If you know less than others it just means you can still learn more than they can.
 
10 smacks! Hell...
 
Anonymous
@Huy You are right
 
Huy
@AshwinGokhale: You must know, I am always right.
 
5:02 PM
If this is algebraic geometry, then I'm a jellyfish.
 
Anonymous
@Huy You good at integration?
 
Huy
@AshwinGokhale: It depends.
 
@BalarkaSen Clearly it's not.
:P
 
Anonymous
@Huy Since you are a grad student,I must ask you if those kinda skills are of any importance in the mathematics tat you are doin?
 
Huy
@AshwinGokhale: It really depends on what you mean by "integration".
 
Anonymous
5:04 PM
@Huy The analysis one
 
Huy
@AshwinGokhale: I know that, but I don't know what you mean exactly by that.
 
Heya @Alizter
Whatcha upto?
 
Relaxing. I had a chemistry exam today.
 
Anonymous
@huy it's those tecchniques
 
@Chris'ssis that must cost a lot !
 
Huy
5:06 PM
@AshwinGokhale: Which ones?
 
@BalarkaSen Yesterday I had a problem with a triangle. It was very embarrassing. Turns out, the question was wrong by stating it was right angled.
 
Anonymous
@Huy LOL all those 1 billion integration problems
 
I have not done any algebra of analysis in a while.
 
I have problem with triangles everyday, @Alizter
 
Huy
@AshwinGokhale: I have never seen a 1 billion integration problem before, can you show me one?
 
5:07 PM
@Alizter I'd like to study "algebra of analysis"
 
Anonymous
@huy *problems?
 
Back.
 
@BalarkaSen add in some number theory and we have a new field.
or one that I have not heard of anyway.
 
@Hippalectryon Well, yeah, it costs some. :-)
 
Huy
@AshwinGokhale: Can you show me them?
 
Anonymous
5:08 PM
@huy you ain't getting me!
 
@TedShifrin It's funny how you spend that much time on Columns spaces. We never talk about them.
 
Algebraic analytic number theory. With extra fries.
 
@Chris'ssis More than 'some' :O
 
@Alizter :P
 
Huy
@AshwinGokhale: I can't really answer your question if I don't know what kind of integrals you mean.
 
5:09 PM
I wanted to study analytic number theory but I have no time
 
@Hippalectryon 100 E for all? Is that much?
 
A book is around 35-50€ on the internet @Chris'ssis
 
Anonymous
@huy all those which require some clever tricks
 
or creativity.
 
Huy
@AshwinGokhale: Can you show me examples?
 
5:09 PM
Actually I think there is some branch like that @Alizter
 
@Chris'ssis How many books ?
 
So instead I am studying fractals
 
Anonymous
@Huy many in MSE are those kinda questions~
 
@Hippalectryon well, not all books are that expensive as those on internet.
 
@Chris'ssis :O That's amazingly low
 
Huy
5:09 PM
@AshwinGokhale: Can you send me the link to one of them?
 
@Alizter I know nothing more than PNT in analytic NT.
 
I guess prices are lower in Romania :/
 
@Alizter lie theory?
 
@Hippalectryon Yeap, they are lower.
 
@Alizter To understand fractals, you need to understand hyperbolic geometry properly.
 
@Chris'ssis I should come to Romania for a day or two just to buy books :D too bad I can't :/
 
@BalarkaSen Oh it is nothing serious
more to do with their computation
 
Huy
@AshwinGokhale: Those kind of integrals, I have no idea how I would start solving them and I never came across anything remotely similar in my work.
 
@Hippalectryon Sure, why not? :D
 
@Chris'ssis Because I'm 16 :-)
 
5:11 PM
@Hippalectryon lol (sure, you're just 16 ...)
 
I tried to study lie algebras 2 weeks ago.
tried
 
I'm still studying
Can't come abroad :/
 
Huy
@AshwinGokhale: I like to use mathematics to solve actual problems.
 
@Hippalectryon ;)
 
never understood those stuff @Alizter
 
5:12 PM
@Chris'ssis You still don't believe me >:c
 
MANIFOLDS <-- such complicated
 
@Hippalectryon sorry ... :-)
 
@Alizter I thought it connected analysis and algebra along with differential geometry
 
@BalarkaSen I need to learn 'basic' algebra properly though
 
After all, even if I sent you my ID card you probably still wouldn't believe me xD
 
5:12 PM
@UserX Maybe manifolds?
 
@Hippalectryon :-))))))))))
 
And that is not just analysis.
 
@UserX first complete the exercise I gave you
 
Anonymous
@Huy like??
 
@BalarkaSen I proved there are only 2 groups of order 4 up to isomorphism
 
5:13 PM
@UserX What is le proof?
 
Oh now I remember
 
You aint gonna like the solution to prove the uniqueness of the klein 4 though
 
Huy
@AshwinGokhale: I'm currently working on the behaviour of fermions in many-body systems.
 
@Alizter Tao is teaching an ANT course next quarter; his (usually very good) notes will be appearing on his blog, if you want to follow along.
 
I was looking at set theoretic constructions of ordinals and the likings.
 
5:14 PM
@MikeMiller I'm in. Thanks.
 
@MikeMiller Oh thank you very much :)
 
Anonymous
@Huy Great
 
@BalarkaSen Just don't ask me about it. :)
 
@BalarkaSen I still have no idea where I needed Lagrange's theorem

5:14 PM
@Huy I get disappointed when I couldn't solve one of those tricky problems
 
@UserX first show your proof
 
Anonymous
*Cannot
 
@BalarkaSen it's brute forcing the table :P
But I can't do that for higher orders. What did you have in mind?
 
Shhhh @Mike
 
Ok.
 
5:15 PM
@MikeMiller they're all order 2 I think
 
@UserX Yes. Why?
 
Huy
@AshwinGokhale: I think people should do what they enjoy doing, as long as nobody else gets harmed.
 
prove it @UserX
 
@Chris'ssis Any new awesome discovery ?
 
@Huy And Queen
 
5:16 PM
@Chris'ssis Except the one with the frac parts
 
Anonymous
@Integrator Are those the ones who are very fond of solving those integration problemds?
 
@MikeMiller i know that an algebraic topologist doesn't really care about loglogloglog x/logloglog x + O(logx) stuff, Mike.
 
Huy
@Integrator: I am not sure what you are trying to tell me with those links.
 
@Hippalectryon What do you mean?
 
I'm not an algebraic topologist.
 
5:16 PM
i won't bother you about it.
 
Anonymous
@Huy You are right and yo are always right
 
@MikeMiller heh
i thought you were
 
Nah.
 
@MikeMiller because I can see it from the table lol. Anyway, bbl 1h30m
 
Everyone needs to know algebraic topology. I just know it.
 
5:17 PM
@AshwinGokhale Kind of
 
Anonymous
@Huy they are the ones who solve most of those tricky problems
 
@UserX forget the table. classify all groups of order 2^167
Now we'll see if you can use the table
 
Huy
@AshwinGokhale: I wouldn't want them to stop if that's what they enjoy doing. :)
 
@BalarkaSen You can't even classify those.
 
Huy
5:17 PM
@Integrator: I see.
 
@Huy :)
 
Should have asked him to classify those of order 35.
 
@MikeMiller sure i can. semidirect products.
 
Anonymous
@Huy Yes sir!
 
4 hours ago, by Chris's sis
$$\int_0^1 \int_0^1 \int_0^1 \left\{ \frac{x y}{z}\right\} \left\{ \frac{z x}{y}\right\} \left\{ \frac{y z}{x}\right\} \ dx \ dy \ dz$$
 
5:18 PM
@BalarkaSen No, there are more groups there than semidirect products.
 
@Huy Don't forget @venus
 
oh ok some are nontrivial extensions
 
@Hippalectryon that one seem nice, isn't it? Newly created. :-)
 
Indeed
 
yeah, and good luck classifying those.
 
Anonymous
5:19 PM
@integrator even she is one of those people :D
 
@AshwinGokhale and @Chris'ssis too
 
like I said, 35 is a good number to give him. :)
 
@AshwinGokhale Kind of!
 
well, probably not. I guess he doesn't have enough technology yet.
 
Anonymous
@Integrator and integratot
 
5:19 PM
he needs to forget about cayley tables
 
Maybe I am over-analysing but all these topology jokes about doughnuts and coffee cups are a bit silly. If a Mathematician needs coffee to run then they could not have the abstract thinking required for algebraic topology if they were drinking a doughnut. Thus making them able to see the differences.
 
@AshwinGokhale ?
@AshwinGokhale I'm new here! Just 25 days!
 
Anonymous
@Integrator That makes two of us :D
 
@BalarkaSen is that a challenge?
 
@AshwinGokhale :)
 
5:21 PM
@MikeMiller perhaps we should explain him this case. otherwise he can't eject that bullshit brute force method out of his mind.
 
Anonymous
@Integrator I am very new that I do not even know where to look for to find out how old I am in this chat!
 
@UserX no, it's an advice. :)
 
Man it's so straightforward
 
Anonymous
*chat room
 
@UserX it won't be when the order gets large enough.
OK, classify all groups of order p^2, @UserX
 
5:22 PM
@BalarkaSen p prime?
 
right
 
no p is number
 
Even order 9 is too hard with Cayley tables. I don't think you can classify the groups of order $p^2$ without some technology you don't have yet.
 
Anonymous
@huy I gtg bye
 
Huy
Have a nice day, @AshwinGokhale.
 
5:23 PM
K, I will when I remember where I read about prime order group
 
Hi @Huy @Ashwin @Integrator @Balarka
 
Bbl
 
Well, you should be able to classify all prime order groups.
 
@Huy Catches Huy after a long time... :D
 
@MikeMiller This is what technology does
 
Huy
5:23 PM
@Sawarnik: Hi.
 
@Sawarnik Hi!!!!!!!!
 
@Huy I had some queries to ask you, totally forgot :/ :/
 
Huy
@Sawarnik: Namely?
 
@Alizter Can't watch.
 
@Integrator A few less '!' could do :P
 
5:25 PM
@MikeMiller Are you at work?
 
@Huy Something on Swiz..
 
yah
 
Huy
@Sawarnik: Take your time. I'll still be around for about 30 minutes.
 
@MikeMiller So you are chatting :P
 
shh
I'm working, I promise.
 
5:25 PM
LOL
 
@Sawarnik Hi -(!!!!!!!!!!!), Now fine?
 
Fine!
@BalarkaSen The 8 smacks disappeared :((
 
11 smacks, you mean
 
11.. wow... someone should have pinned it!
 
@UserX OK, here's your order 4 group classification : G be your group with |G| = 4. Let x be an elt of G. If it's of order 4, then there exists 4 elements 1, x, x^2, x^3 in G and as |G| = 4, G is all of <x>. If it's of order 3, then the group generated by x, namely <x> = {1, x, x^2} has order 3 but as this is a subgroup of G, Lagrange says this can't happen as 3 doesn't divide 4. Then x has order 2. This means every element has order 2. You can easily check that this is $\cong$ to Z_2 \times Z_2
 
5:28 PM
@anon rules got untagged
 
@Hippa: You should. That's the image (maybe you call it range) of the linear map.
 
Oh i that all ?
We do call it Image
 
@TedShifrin WHat about the row space ?
 
5:30 PM
what the hell
 
That's the image of the transpose :P
 
nobody starred that
 
@BalarkaSen :P
 
@TedShifrin >.>
 
Huy
@Sawarnik: Why would you be jealous?
 
We'll wait for an adult to repost it, @BalarkaSen
2
 
@Integrator Why did you tag me?
 
@Huy I never get to hear it once.
 
@TedShifrin And the right/left nullspace ? Is it just the $X$ such that $AX=0$ // $XA=0$ ?
 
:O :P
 
5:31 PM
sigh
smacks everyone
 
@Venus ??
 
@Hippa: "noyau" (kernel) of map and of its transpose
 
Huy
@Sawarnik: Why not?
 
@TedShifrin you can't ignore me. whaaa.
 
@TedShifrin Oh ok
 
5:32 PM
 
@BalarkaSen what about throwing tables?
@Alizter Veritasium? Lets see.
 
@TedShifrin We don't see the projections at that time though
 
@Integrator Nice footage. But I wouldn't kiss a boy for that
 
@TedShifrin Wee see it with euclidian spaces
 
Hi @TedShifrin
 
5:33 PM
I'm doing projection matrices specifically tomorrow, @Hippa.
 
Huy
@Venus: What would you kiss a boy for then?
 
Hi @Alizter
 
Who is from US here?
 
@Venus You're a girl then?
 
'Muricuh
 
5:33 PM
@Integrator -_-
 
@TedShifrin Why do you record your classes ?
 
@Mike: It would seem I've added very significantly to the variance (or standard deviation) of the age in here.
 
@Huy If he is my boyfriend of course. I ain't kiss a random guy
 
@TedShifrin I think it's been going down lately... I guess I'm getting too old to be here too.
 
Huy
@Venus: Did you never kiss a boy before he was officially your boyfriend?
 
5:34 PM
Someone decided to do it last spring @Hippa, partly to help out a physics major who had a conflict one of the four days. And so then people volunteered to record the first semester lectures this fall. After that, no more.
 
@MikeMiller your bones are getting too old for chatting, yes
 
@TedShifrin That's sad :/
 
@Mike: Maybe you and robjohn and I need an old folks room.
 
I was getting free classes
 
When does your term end, @Ted?
 
5:35 PM
Can I flag/close this as off-topic?
 
But you don't even like them, @Hippa :D
 
@Sawarnik ??
 
A week from today is the last class, @Mike. Then finals.
 
@TedShifrin What makes you say that ?
 
@TedShifrin Dr. Sonnhard will join you, lol :D
 
5:35 PM
@TedShifrin Ah, we're close to that. Next Friday is the last day of classes, then finals for us.
 
@Huy As far as I remembered, I didn't
 
@TedShifrin Why would I watch 50h of video if they were boring ?
 
I have a week to do nothing between my last class and my calc final. I hope I can finish it all by the day after so I can go home...
 
@Huy Officially?
 
Huy
@Venus: Very interesting. Over here, most people would kiss others before going into a committed relationship with them.
 
5:36 PM
@huyI'm just not kind of that girl
 
Tu te plains toujours, @Hippa :P
 
@TedShifrin Mais pas de tout !
 
ok, @Huy ... enough.
 
@Huy This is Asia OK?
 
Huy
@TedShifrin: What's wrong?
 
5:37 PM
@Venus Where in Asia?
 
@Huy The discussion you're having...
 
@Huy I think It's not me who who is desperate!
 
Huy
@teadawg1337: You don't have to read it if you don't want to?
 
You can move it to a private room if you insist, @Huy.
 
@Sawarnik Should I answer a similar question over & over?
 
Huy
5:38 PM
@TedShifrin: How is it different than talking to people about where they're from and what their country is like and how their day was?
@TedShifrin: Nobody ever complained to me about doing the latter?
 
Malaysia @Sawarnik
 
I second @Ted
 
I'm not offended by it? I was just guessing what the answer would be... Although it is very inappropriate
 
This is not supposed to be a dating room ... and this verges on that ...
11
 
@Venus Ok :D
 
Huy
5:39 PM
@TedShifrin: She and I both are in a different relationship, I'm just talking to a person on the internet.
 
@Ted Any good questions today?
 
@Venus Recently there was this headline on your police force.
@Huy Why do you think I would?
 
@Huy 5 to 1, you're outvoted.
 
@Sawarnik What headline?
 
I've been busy with students and exams, @Mike ... you can grade if you'd like.
 
5:40 PM
No thanks.
 
Last time I checked, this was Mathematics.SE
 
I finished the only matrices I do at school this year :(
 
I'm hoping I can get all my grading done day of... work hard for 8 hours and be done with it.
 
Matrices are never finished, @Alizter.
 
@teadawg1337 It still is.
 
Huy
5:41 PM
@TedShifrin: I honestly don't get it. If I was asking a male person on MSE about these kind of things, people would realize I'm just asking because I'm interested in how people in other countries interact with each other and on MSE I can talk to people from many different countries. It doesn't have to be dating attempts immediately, has that thought ever occurred to you?
 
@TedShifrin Yes they are. They won't teach it this year anymore.
I can learn my self grant you that. And the subject is ever expanding.
 
@Sawarnik I was trying to make a point...
 
But that is not what I meant.
 
Without commenting on content, @Huy, your last sentence is phrased really rudely.
 
Looks like @Huy is getting into his childish anger mood again..
 
5:42 PM
@teadawg1337 @TedShifrin I think nothing's wrong with @Huy questions. It's so-so to me
 
@Huy is almost always rude.
 
Huy
@MikeMiller: I'm sorry if it was, it wasn't intended to be phrased rudely, I'm not a native.
 
No, you are.
To me!
 
I don't want to debate it with you, @Huy. The fact is that we have an extraordinary number of kids under 16 in here and this room is supposed to be focused on math one way or another.
4
 
@Ted Me!
 
Huy
5:43 PM
@TedShifrin: Then you could say that without trying to imply other things, which are untrue.
 
But, frankly, I don't care. I'm going to grade papers ...
 
@TedShifrin Good on you!
 
@Huy I think what's trying to be said is sure you can say these things, but the majority of the room does not want to have this sort of conversation in this room so please don't have it in this room
 
@Integrator See what have you done by posting that video? :D
 
Huy
@DanZimm: I get this, but instead of saying just that, he implied other things, which I don't think is the right way to say what you said.
 
5:45 PM
@Venus :(
 
I frankly consider leaving this room as most of the time I open it up, I see a load of nonsense jibberish like the discussion @Venus and @Huy were having. It's supposed to be about mathematics.
 
Please, just drop it guys... Enough is enough, let's talk about mathematics...
 
@Huy O.o, if you understand the point he's saying then stop! :P
 
Huy
@BalarkaSen: Good for me it's the first time since days I've been kind of active in the chatroom. Imagine if I was here more often!
@DanZimm: I stopped, if you haven't noticed.
 
@Huy You'd be muted!
 
5:46 PM
so how about them dodgers
 
Huy
@Integrator: Oh my!
 
@BalarkaSen OK, I'm sorry then for adult topic discussions between me & @Huy. Is it okay now?
 
@MikeMiller I'm not really a baseball fan anymore but are they still playing, aren't they out of season?
 
Dodgers aren't playing right now. How about the Patriots?
 
@Huy :P
 
5:48 PM
I have very nasty things to say about the patriots, and as mentioned above, there are kids in this room.
 
Relationships off and baseball on. Great.
 
We turned the baseball off, @BalarkaSen, now we're on football.
 
My bad. I live in New England, so it's home team, you know.
Raiders fan?
Or Giants?
 
Huy
@Sawarnik: I think you need to realise that it is difficult to know what people mean on the internet. What might appear to you as someone "raging" or "being mad" could just be someone trying to discuss a specific matter. ;-)
@Sawarnik: I don't want anyone to distribute my photos I upload on my private profile, like you did.
 
@Huy Ok.
 
5:50 PM
@Huy TRUE!
 
Eagles, @KitFox.
 
I didn't really do it, but fine.
 
@MikeMiller I see.
 
I'm still sour about a decade ago.
 
Is anyone familiar with weak $L^p$ spaces? If they are can they point me to any decent resources?
 
5:51 PM
Cricket, anyone?
 
@MikeMiller Understandable.
 
NO @Sawarnik
 
@BalarkaSen What is wrong with you? Not everyday we discuss about math. Have fun young boy! :-)
4
 
:(
 
Huy
@Sawarnik: You posted a picture I uploaded on Facebook twice in this chat, but if you can't remember it, I am sorry for your bad memory.
 
5:51 PM
@Venus Go to the fun room
 
@Huy k.
 
tried to turn it to math
 
@BalarkaSen You're just too serious for a teenager
2
 
@DanZimm The crowd isn't right.
 
You contribute to nothing compared to the rest of us here @Venus. You have no right to advise me.
 
5:52 PM
Wow.
@Venus Socially inept mathematician.
 
aight well have a nice day, good luck grading @MikeMiller
 
Ok, I have contributed enough to this nonsense. Goes on mute.
 
or @TedShifrin can't remember who was grading
 
Huy
Alright, I have to leave for dinner. Have a nice day everyone!
 
@BalarkaSen So what is your contribution here?
 
5:53 PM
So can someone explain to me how to calculate the volume of a rotational solid?
 
Both of us, @DanZimm, but Ted's is probably more painful.
 
I'm outta here.
 
@Balarka Toodles!
 
OK, I'm out too.
Bye guys. Have fun with your world ^^
 
@Venus Mathematics IS my world :P
 
5:55 PM
@BalarkaSen Noodles!
 
@teadawg1337 You're world is so rigorously defined.
 
@Huy If you're interested in having a conversation with me other than math (any topics). We can talk in other room. I'm okay for that ^^
 
@Venus owww
 
@Integrator It provides a bit of predictability imo :)
