Mathematics - 2017-09-16 (page 7 of 9)

@AndreasAlmgren Well, from whatever I know about the various parts of the world. Culture, laws, climate, natural disasters, economy, etc. I don't have any exact statistics, but it is simply what I think and want to express now.

Dodsy

@BalarkaSen is math related to science

Balarka Sen

@Dodsy meth is the language of the universe

Dodsy

oic

Daminark

@Balarka I'll try to see if I have it as well, if not I'll let you know

Balarka Sen

Ok, coolio

Hatshepsut

8:29 PM

@LeakyNun thanks

Jasper

@SteamyRoot Yup, but I really wanted to do the uniformisation and Runge theorems, so I chose Forster's book instead.

SteamyRoot

@Daminark Well, I've never compared it to another book on the same subject, but it felt pretty algebraic

Don't remember any PDE's in there :P

Daminark

I see

Dodsy

What are you guys doing this weekend?

Daminark

@BalarkaSen lay it on me

Dodsy

8:30 PM

other than being little scamps.

Andreas Almgren

@Jasper. No need for statistics :P

Daminark

@Dodsy are there other things to do in life?

Dodsy

:D

Jasper

If you guys want an extremely analytic book on Riemann surfaces, go for Napier and Ramachandran: Introduction to Riemann Surfaces.

It is a very new book and not well known yet, and is over 500 pages.

SteamyRoot

@Dodsy Getting asked out by a student :P

Andreas Almgren

8:31 PM

@Dodsy Trying to survive the best I can through this miserable life. Yourself?

Jasper

However, half the book is on the prerequisites.

Dodsy

:o

Balarka Sen

@Daminark Uploading shit. It's 18MB

Daminark

@SteamyRoot wait wait whaaaa?

Balarka Sen

not too bad

Dodsy

8:31 PM

Okay one situation at a time:
@SteamyRoot dude.
@AndreasAlmgren cheer up!

Leaky Nun

@SteamyRoot warum studierst du mathematik?

Jasper

Another very analytic book is Varolin: Riemann Surfaces by way of Complex Analytic Geometry.

Daminark

@Balarka where should I receive it?

Andreas Almgren

I was tapping on my irony a bit @Dodsy

SteamyRoot

@LeakyNun Bauchgefühl

Balarka Sen

8:32 PM

at your university email

Dodsy

Ah, good!

Daminark

Sick

Dodsy

@SteamyRoot sprechen zie deutch?

Andreas Almgren

Någon som kan prata svenska?

SteamyRoot

@Dodsy Ein bisschen.

Jasper

8:33 PM

For once, someone speaks Swedish in this chat.

SteamyRoot

I can totally understand that sentence

Jasper

@BalarkaSen I do know some Tamil curse words, lol.

Leaky Nun

@AndreasAlmgren @KasmirKhaan talar svenska

SteamyRoot

but the only Swedish I actually know is Va Fan :P

Dodsy

@SteamyRoot oh, wegen der leaky nun, ich denke du waren in Germany.

Leaky Nun

8:35 PM

@Dodsy ich mag Sprache lernen :)

Andreas Almgren

@LeakyNun I spoke a bit with @KasmirKhaan a bit yesterday ; )

Dodsy

@LeakyNun Gut!

Leaky Nun

@AndreasAlmgren god

Andreas Almgren

God?

You mean "bra"?

Dodsy

@LeakyNun as you can see, my german is spotty at best. :P

Daminark

8:36 PM

So apparently Donaldson is more difftop-y, Forster is sheaf-theoretic, Miranda is more alg geo

Leaky Nun

@AndreasAlmgren heh

Dodsy

but my grandmother was born in germany and we speak german to each other sometimes.

Daminark

I'm fine with any tbh, might use a mix

SteamyRoot

@Dodsy Ich bin Belgier, also Deutsch ist meine dritte Sprache

Leaky Nun

what is the difference? @AndreasAlmgren

Jasper

8:36 PM

@Daminark And Napier/Ramachandran and Varolin are more analytic.

Balarka Sen

@Daminark sent

Dodsy

@SteamyRoot Ah, I see.

What is your second language then?

SteamyRoot

French

Leaky Nun

@SteamyRoot aber du sprichst es besser als uns :3

Dodsy

wow, crazy.

I hate french

Quebec french that is.

:P

Daminark

8:38 PM

I know a few words of French, my dad said I sounded South African when I spoke it

Balarka Sen

daminark can rap in french

Leaky Nun

how does your dad know what South Africans speak like

Jasper

Pourquoi me reveille o souffle du printemps

SteamyRoot

@Daminark It's totally fine if she already graduated from her Bachelor's degree and I won't be teaching/TA'ing her anymore, right? :P

Jasper

That's a French aria, lol.

SteamyRoot

8:38 PM

Ha, Afrikaans is pretty much Dutch with the grammar thrown out the window

Leaky Nun

looks like @Jasper is about to sing for us

Daminark

Oh I mean that totally works

@Steamy

Leaky Nun

@SteamyRoot until you realize that "you" in Dutch is "u".

Daminark

@Balarka Dank(e)!

Dodsy

Bonjour, Je mapelle Dodsy.

je ne sais pas.

Jasper

8:40 PM

@SteamyRoot Did you know that Andrea Bocelli sang Because We Believe with Marco Borsato in NL?

Balarka Sen

i guess the anagram for steamy's name becomes relevant now

Dodsy

This is all I know.

Daminark

@BalarkaSen to the tune of FTL

Andreas Almgren

"god" means either kind of "a kind person" or "tasty". "bra" means something that is "good" @LeakyNun

Dodsy

I took french for 5 years.

SteamyRoot

8:40 PM

@LeakyNun Only the polite variant

Leaky Nun

@AndreasAlmgren so "god dag" is a tasty day?

Dodsy

Kan ich haben ein baguette?

SteamyRoot

@Jasper Yup, was pretty great :D

Leaky Nun

lol, @Dodsy

Dodsy

French is hard @LeakyNun

german is much easier :)

Daminark

8:41 PM

@LeakyNun I think that was just the stereotype when he was in France? That or he knows some such people

Andreas Almgren

It depends on the situation you are using "god" in, you are using it wrongly @LeakyNun

Jasper

Surprising that french windows are actually doors.

SteamyRoot

@Daminark That was meant for the other message and not about the Afrikaans, right? :P

Leaky Nun

@AndreasAlmgren svenska @_@

Andreas Almgren

I need to quit

Balarka Sen

8:42 PM

the god memes are tasty, yes

2

Daminark

Yup @Steamy

Dodsy

@AndreasAlmgren what language is this? Swedish?

Jasper

@AndreasAlmgren Quit from what? You mean leave the chat?

Leaky Nun

@Dodsy right

Dodsy

hm interesting.

Daminark

8:43 PM

@Balarka r/nocontext

Dodsy

And yet I still starred the comment @Daminark

SteamyRoot

@Daminark Good. Now just hope my colleagues and supervisor approve :^)

Daminark

@SteamyRoot do you need their approval? Like if the person in question is no longer a student don't those considerations basically go down the drain?

SteamyRoot

@Daminark Well, technically she's still a student at the university since she'll be doing a Master's degree. But at a different campus.

Daminark

Ah. I mean still doesn't sound like there's reason to be worried but sure I guess

Balarka Sen

8:46 PM

Yeah that standard bias considerations are not really a problem anymore

So that should be fine

Leaky Nun

How do you pronounce Sylow?

Daminark

Is there an analytic inverse function theorem

See-lov @Leaky

Leaky Nun

people who can't pronounce "y" :c

SteamyRoot

[ ˈsyːlɔv])

Daminark

If I'm being careful that is, oftentimes I just sat See-low

Leaky Nun

8:50 PM

@SteamyRoot right, both German and French have /y/

Daminark

"Sigh low"

Balarka Sen

@Daminark yeah

you can prove it

(trying to analogize the proof for smooth functions is NOT the right approach)

Daminark

You can probably do it similarly to real functions

Like just R to R

SteamyRoot

Suuh-lohv I guess.

Daminark

Maybe with real part positive

Actually I should probably learn the open mapping theorem for complex functions first

That'll make life easier

Leaky Nun

8:54 PM

I like to think of the subspace of all complex functions generated by the basis $\{e^{kx} \mid k \in \Bbb C\}$

the derivative linear transformation preserves the basis elements very perfectly

nice linear DE's would be a linear algebra equation on said subspace

Dodsy

Me and gf bought baking powder and now it's missing :(

2

it costs like 5 bucks doods

Balarka Sen

♪ baking soda, i lost the baking soda ♪

Dodsy

Also can someone explain to me "cancellation equations"?

is it basically pointless?

Jasper

@Dodsy What context?

Dodsy

perhaps stewart is simply restating a point in a stupid way?

Balarka Sen

8:58 PM

What's the context?

Ok, I got sniped

Jasper

Nifty

Dodsy

imgur.com/a/0Sg2C

is he just trying to say that if you put $f^{-1}(x)$ and $f(x)$ together you get x?

SteamyRoot

$f$ and $f^{-1}$ "cancel eachother out"

Balarka Sen

Yeah, they're defining inverse functions.

Jasper

They are just saying that the inverse function cancels out the effect of the function.
