@JonasTeuwen can you compute delta function squared? :)
 
Wait... Are you trolling me?
 
no no
I was interested in it some time ago too
 
I have written a post about it.
 
yes, but it is well defined in nonstandard universum
 
A what?
 
8:09 PM
? delta*delta is not an element of standard universum with ZFC
but in nonstandard universum it is a well defined thing
 
That would not make any sense, you would have stuff like $\langle \delta^2, \phi \rangle = \langle \delta, \delta \phi \rangle = \delta(0) \phi(0)$ and there is no sensible way to define that.
...?
Sounds like nonsense to me, but I know very little about set theory.
 
there is, you can see Albeverio's book on nonstandard analysis with applications to stokhastic processes. It is very interesting
 
Hmm, nonstandard analysis, no thanks.
 
why?
 
If you know the answer, why do you ask me?
And I thought nonstandard analysis should prove the same theorems...
 
8:13 PM
I look on nonstandard analysis as on tool that allows us to extend some constructions that is not possible within standard analysis (in general). for example the multiplication of 2 generalised functions. I ask you because it is very interesting area for me
 
But if you know it can be defined, then why don't know you what the solution is?
 
The solution is "a monster" that acts in nonstandard universum. Nothing more useful for standard analysis we can't say.
 
which answer do you need?
 
8:52 PM
@tb On second thought I think I don't see this. I have a function on $\mathbb R$, how do I turn it into a function on $\mathbb C$?
 
Depends on what you want it to be right, does it have to be holomorphic?
 
Assume I start with $f$ analytic.
 
Solve the Cauchy-Riemann equations.
 
What do you mean? I have $f: \mathbb R \to \mathbb R$.
For CR equations I need two functions.
 
Yes, you need to find one that satisfies that equation.
 
8:58 PM
And how do I turn $f(x)$ into $f(x,y)$?
 
You can just overload it and see if that works? 8-).
 
Poor me.
 
if it's analytic why not just plug in z=x+iy
 
You can have functions that are real analytic, say $(1 + x^2)^{-1}$ but not complex analytic as they have poles :(. Damn poles.
 
well, it's meromorphic, good enough
 
9:01 PM
@anon Not sure.
 
(err, I mean plug into the power series)
 
Operator overloading...
They call that functional calculi.
I prefer the name "operator overloading".
Kitty.
 
Meow.
 
9:26 PM
Woof!
 
Did you put yourself on fire, @AsafKaragila?
 
Looks like Teddy's gone to sleep.
I think that's a sign that it's bed time here.
 
@MattN ta-daa!
 
Heh. : )
I was going to badger you with analytic functions but now I'm too tired.
Also, the drink doesn't help.
 
another time, then. Sleep tight :)
 
9:40 PM
Yes. Thanks : ) You too.
Will I see that you stayed up all night again tomorrow morning?
 
Thanks. I hope not...
 
How many Marys are there?
 
How many? Six.
 
I thought this one owed me an accept but then I looked at her profile and it turns out it's a different one.
@Gigili : D
 
I'm so tired.
 
9:42 PM
@AsafKaragila You probably just need a beer or something like that?
 
@tb Yes neither do I. You won't get a carrot otherwise, you know. : )
 
Already had a beer.
I only slept like two hours...
 
Hmm... Tough problem. Maybe you need something stronger.
I bought this Dutch whisky just because it's Dutch.
What a waste of perfectly good money which I could have spent on something decent.
 
Night folks, see you tomorrow.
 
Good night.
 
9:44 PM
Night.
 
Shalom, Asaf.
: )
 
WTH, you address someone as "her" just because they used female name for their display name but when I say I am female some people .. Let's not get into that again. Use "it", I DON'T CARE.
 
Gute Nacht, Matt.
 
Good night @MattN.
 
Why is it complaining about "her" or "him"?
 
9:46 PM
@JonasTeuwen Don't you know that the Dutch only do three things right: Mayonnaise; becoming a pirate ghost ship; and crumbling at the hand of the Nazis (although the Belgians are better at the last one).
Whisky is not something that the Dutch do well.
 
So concerning the last I am a double failure?
They don't do mayonnaise right, seriously.
The Belgian mayonnaise is way better.
I like it sour, not sweet.
 
Yeah you do.
 
@anon: okay, we've both hit a new lhf :-)
 
I keep forgetting what a "lhf" is. It was a user on freenode.
 
I'm voting for anon, because he needs to be trusted already.
 
9:49 PM
I was going to say, my last two choice of questions to answer have been really fuckin lazy :D
 
@JonasTeuwen lhf = low hanging fruit
@anon mine, too :-)
 
Oh.
I vote for both.
 
There are only $3^3$ many users we can trust.
 
Plz giev me 15k.
 
@AsafKaragila is that all? wow
 
9:50 PM
At the moment, I wear a skii mask on MSE.
 
@robjohn Yes. This is why I trust you with deleting answers.
@anon So once you get to 20k you're gonna change the user name to your real name and all that?
 
@JonasTeuwen sure, just let me set up a bounty ;-D
 
:D...
 
@Asaf: My real name? No. I've thought of some name-sounding aliases though. Daniel Overfield, Patrick Lapross, Carter Living, James Wellspring, ...
 
Buck Rambone?
 
9:52 PM
@anon Lance Hardwood?
 
@AsafKaragila That's my porn name.
 
@anon Rod La Fontaine?
 
Beinrich Bimler?
 
What, is my name CW now?
 
@anon Chuck Waggoner?
 
9:56 PM
Chuck Worris.
 
Danny Glover.
 
Speaking of which, I know what my name will be come one weekish from now.
But you'll have to wait for that.
 
Billy Jean.
 
@AsafKaragila Have you seen Fawlty Towers?
 
10:01 PM
I guess you now have to help me to hit 1k
 
@anon nipple?
 
@robjohn I have seen parts, but I don't remember much. I should give it another watch.
 
@AsafKaragila There are only 12 episodes, but they are hilarious.
 
Yeah.
There was this bit of Fry and Laurie when they gave Cleese a prize for the series.
 
:3976367 Yo momma failed!
 
10:05 PM
I disagree.
 
@AsafKaragila I think we all can put our disputes behind us, and enjoy the clip
 
I know that bit.
 
10:23 PM
I am going to sleep now.
See you tomorrow, folks.
 
@anon: I should learn about the Laplace Transform. I've never had a class that covered it and I have never studied it independently.
 
It's not that hard to learn from Wikipedia and scratchwork imo.
 
@robjohn What...?
So you did your graduate work in harmonic analysis and you haven't learned the Laplace transform? 8-).
Anyway if you know the Fourier transform it is easy.
 
@JonasTeuwen I did everything with the FT, and never really looked deeply at the LT. It looked similar, and I figured that I could probably pick it up like a new programming language :-)
 
Yes, that is a correct assumption :-).
 
10:29 PM
I just never have :-)
 
@robjohn Well I do not see why you would intentionally avoid learning it
 
@N3buchadnezzar I have not avoided it, I have just never had the need nor spent the time to look at it.
 
It can make some integrals and PDE much easier ;)
 
Hmm, only very basic PDEs.
 
@N3buchadnezzar I have spent time doing the theory behind PDEs and not actually solving them. Most of that can be done with the FT, evidently :-)
 
10:31 PM
Like the $$ \int_0^\infty \frac{\sin x}{x} \mathrm{d}r $$ can be solved by introducing the dummy variable $e^{-tx}$
And this strange thing comes from knowing ones laplace transforms :p
 
@N3buchadnezzar or using contour integration.
 
@robjohn Shhh!
 
I have never seen a situation where only the Laplace transform works.
It is sometimes convenient in some engineering problems.
 
I really want to learn that but alas, I have not been able to yet.
 
Where everything is linear :-).
 
10:32 PM
@JonasTeuwen and that is why I probably never felt the need to look into it. It's like a one-sided, rotated Fourier Transform.
 
It is a one-sided, rotated Fourier transform :-).
The theory behind PDEs is way more interesting than the Laplace transform by the way 8-).
 
I was thinking of reading an introduction book to complex analysis in my vacation, but have not been able to decide on one yet.
 
Stein & Shakarchi.
 
@N3buchadnezzar complex analysis is a beautiful thing. I would suggest reading about it.
 
10:34 PM
I was thinking about looking into Schaums or "Visual complex analysis" but yeah
 
@tb Wow!
 
@JonasTeuwen I will look into that one =) I heard it could be a tad dry, but yeah. I am clueless wabbling dofus.
 
Or Greene & Krantz.
 
@N3buchadnezzar and you might be able to get help with anything that is confusing :-)
 
I think robjohn would approve.
(Krantz & Stein)
 
10:36 PM
@JonasTeuwen anything by Stein or Krantz I would recommend.
 
Yes, me too.
But I didn't have the honour to meet them :-).
 
@JonasTeuwen Krantz is very personable. Stein is a bit harder to get to know.
 
I would like to avoid any book written by a maniac with an intense urge to throw theorems at me,
I have had enough bad experiences with that already :p
 
@N3buchadnezzar throw theorems?
 
Like 200 theorems at each chapter :/
 
10:38 PM
@robjohn Harder as in impossible or just takes a bit longer?
@N3buchadnezzar But you're a mathematician. You should eat theorems for breakfast.
 
with mayonnaise?
 
@JonasTeuwen not impossible. It is easier if you have done something significant. I think I only proved one thing that made him raise his eyebrow.
 
@JonasTeuwen I prefer my theorems with lemmas and proofs. Theorems alone tends to get a tad dry.
 
Haha.
@tb Yes.
 
@N3buchadnezzar lemma-nade?
2
 
10:40 PM
@robjohn So he's not easily impressed :-).
 
@JonasTeuwen It does take a bit of effort to get his attention.
 
@robjohn You should try Goldbach
 
This guy doesn't make much sense, does he?
 
@tb Do you remember that guy on MO which copied a question of someone else on MO and got banned?
 
vaguely
 
10:47 PM
@tb Hmm, maybe to Yoda.
 
His profile said something about "working for the USA army in Area 51" or something like that.
Anyway, Matrix = that guy. He's from Morocco, which is probably why his English is bad.
 
He works on harmonic analysis?
 
@AsafKaragila oh, I see. already had that encounter...
 
Heh.
Huh?
 
Never mind, I had to say it. And you just proved it.
Don't make me flag one of your messages tonight, you egocentric.
 
10:55 PM
Never mind, I had to say it. And you just proved it.
 
Huh, nice to see the removed message.
 
I still hold to that thought, let it be clear. I'm just too tired and sleep deprived to get into intense internet arguments.
We can do that tomorrow, if no one has stabbed you in the neck until then.
 
Go to sleep and make a world happy.
 
Bite me.
 
Sorry, I'm not interested. Ask someone else.
 
10:58 PM
Me me me
jumps intensly up and down
@AsafKaragila And did you not say good night 30 minutes ago? It is way over bedtime for you!
 
1 message moved to The Bin
@N3buchadnezzar I decided to grab something to eat before sleep...
 
So I made me a light sandwich...
 
Mustard, pickles, pastrami...
 
11:03 PM
With mayonnaise?
 
I hate mayonnaise.
 
Good, more mayonnaise for me.
 
@AsafKaragila With lemma-nade?
 
@N3buchadnezzar No, with lemon-aid.
 
I once tried lemon-acid, it is not quite the same.
cool aid >>> first aid
 
11:04 PM
@N3buchadnezzar Try lemon scented Pledge! it's good for you.
 
Did I just jump the shark here?
 
I got used to it, abusing features is your habit. Enjoy yourself.
 
Thanks for the suggestiom!
 
@Gigili Oh, I just think that your remark was offensive.
Not enough for a flag, but surely enough for this sort of "abuse".
@N3buchadnezzar I drink tons of lemonade??
 
Hmm, I can't seem to recall to have seen Gigili here before.
Well, vaguely maybe.
 
11:07 PM
Gigili's been here numerous times.
 
Well if you want to talk about getting banned from chat, this chap here knows all about it.
 
You were just too sober to remember that...
 
Probably didn't leave a deep impression.
 
@AsafKaragila I really think you should stop doing that... Whether the remark was offensive or not, I think you've crossed the line of good taste yourself at least twice in the last ten minutes.

11:09 PM
Heh, someone flagged it.
 
And I marked it valid.
 
This discussion needs more St.Patricksday
 
Also marked as a valid flag
 
We need more drunk persons in hèlicôpteurs.
3
 
@N3buchadnezzar I can agree with this.
 
11:12 PM
@Asaf Please refrain from further insults directed at other members of this chat.
8
 
Would this be a good time to lighten the mood by my amazing drawing ?
 
@N3buchadnezzar Lets see!
 
@N3buchadnezzar Yes.
Wow, this is ... deep.
 
It isMmm
Ops
 
@AsafKaragila He didn't exclude the option of insulting yourself...
 
11:15 PM
Let us try that again
 
@anon I don't think so.
 
I have set a tornado horn as an alarm clock. Connected it to my stereo installation. I hope that wakes me up.
Well, as the alarm bell.
 
Or set it 20 minutes earlier and assume the police arriving will wake you.
 
Hmm, the artistic interpretation of the Texas Chainsaw Massacre?
 
11:22 PM
Its time to play "Guess what the heck he has drawn this time" !
 
I see Link carrying a musical instrument of some sort.
 
You should get an iPad or some other tablet pc and a stylus. Then you can make this type of nonsense all day.
 
@JonasTeuwen Nonsense ? Its Art
And FYI it is nighttime now, the only time I have for fooling around.
 
That's why you need an iPad, then you can do this during classes.
 
I drew something from UK, if that helps.
 
11:25 PM
I need to get up in five hours 8-(.
I really will need the tornado horn.
K. Off to the shower. Good night guys!
 
Pfft
@JonasTeuwen G `night
 
'night, Jonas
 
You should probably install bagpipes.
 
Night.
 
11:41 PM
@anon: I got accepted on the lhf only because I was 19 seconds earlier.
 
I've had a couple other lhfs, no worries.
 
@N3buchadnezzar and you gave up art to be a mathematician?
 
then again, with a +15 I would have got 200 by now...
 
@anon Ah, but I don't count the +15 since it doesn't count toward capping. I am at 120 (+30). I have 17 minutes, so I don't think I will get 80 more.
 
It counts toward Epic, or so I'm told.
 
11:44 PM
@anon That it does :-)
and I bet you'll make it ;-)
 
If that badge were as easy as people using the word "epic" these days make it sound we would all have it already!
ah, there it is, I can retire now.
 
@anon: that's capping :-)
I have gotten a lot of answers recently with almost no votes. I feel weak.
I must try harder, grasp for more low hanging fruit :-)
 
it's all about being in the right place at the right time :-)
 
gee. I just noticed that last time I capped was on December 15th. Hit the 200 mark only once this year (well, that's not a surprise, but still...).
