Seriously, I just got a downvote on math.stackexchange.com/a/191573/31475?

Or an up and a down at the same time

I think maybe it was more someone upvoting and then wanting to un-upvote

I am always downvoted

I was downvoted once, but regained my reputation by deleting the post.

I'm not deleting a post with 32 upvotes :D

Don't you get a badge for that?

I've often thought about intentionally writing a wrong answer, so I can delete the post and get a badge.

Does deleting a post give a badge?

I would, of course, never do such a thing. Often my stupidity is purely authentic.

@Matt Let $(X,\mathcal{A})$ be a measurable space and $\mu$ a measure thereupon. Then let $F(A)=\int_{A}f\mathrm{d}\mu$ -- where $A$ is a measurable set in $X$ and $f:X\to[0,\infty)$ is a measurable function -- is $\mu$-absolutely continuous. The inverse is provided by the Radon-Nikodym theorem. I think this is all how far one can get from there without any assumptions on $f$.

So close. I had -2 votes and I deleted it.

Hi Math!

I wanted to let you know that we're having a small chat-party!

Come visit if you like :D

It's a fun time. There might be Gangnam Style.

:D

@Aarthi Hmm, that

is not a small party.

okay so it's a big party

but it's a nerd party!

the best kind of party

later we might even play settlers of catan or something

@Aarthi Oh good!

@JayeshBadwaik i aim to please. :)

@WillHunting Hello William!!!How have you been?

lol, William.

@GustavoBandeira quase levei um susto!

@MeAndMath ??

@ParthKohli why?

@GustavoBandeira boogie math

@MeAndMath =)

Mas foi um susto logarítmico ou um susto exponencial?

@GustavoBandeira $e^x$

@WillHunting Change to a weirder name.

@WillHunting Am I one of them?

Like Potato lo Paco.

@WillHunting stop it...

@WillHunting with mistery (W)

@Will Stop breathing.

@WillHunting :D

Bananery.

@WillHunting c'mon...

@WillHunting Easy, just search the log!

Of course there is. I'm the moderator, I can see secrets in chat.

Search the log, William.

Search the logs, Bill.

C'mon, now search the logs!

A comic tragedy?

It can't be that bad.

@MeAndMath Eu tenho impressão de que ele que pescar na curiosidade. xD

@GustavoBandeira é,isso aí..num é nada.

@WillHunting Don't try and tell me what I can and can not imagine.

No Na'vi language, please. @MeAnMath @GustavoBandeira

@JohnJunior HEY YO! AVRIL LAVIGNE!

If people do not speak English here, I will flag them. I am serious!!

@ParthKohli Oel ngati kameie

Let's freak out!!!!!!Aqui tem um bando de louco!

@WillHunting Yep.

Kanabuie shabora partogli.

lol, that is the real Na'vi language.

Kaburarti cachaçari si traveco pinto sosco!

Same here

@GustavoBandeira XD

I know portuguese, english and spanish and I'm learning Deutsch.

@MeAndMath What about Klingon?

मुझे हिंदी भी आती है. :)

@GustavoBandeira I tried to learn elvish...

Me and math: I know english, Javanese, Spanish, Japanese, Chinese and Akkadian!

@WillHunting yes.

@ParthKohli However did you type that?

@WillHunting Not much.

@GustavoBandeira Javanese? I thought the name of the language is Java. :P :P

@Jayesh: Transliteration. (not the same as translation)

@JayeshBadwaik Javanese - Is Java in Japanese... Learn things straight, dude...

@WillHunting Java is also a language.

Transposition to the key of G# major.

@WillHunting John Senior is on vacation so what's the confusion?

I went to lunch today with a 2 friends, and I mentioned that I'm usually here at SE. One of the guys asked: "What's SE?" the other replied: "It's a meeting place for nerds" - I looked at him with fire in my eyes: "WTF?! SE IS A PLACE FOR HIPSTERS!"

@GustavoBandeira LOL

@WillHunting Maybe I'll leave then.

@JohnJunior Noooooooooooooooooo.

@GustavoBandeira today a number from Pernambuco called me...

@MeAndMath 9720 1797?

@GustavoBandeira no

@WillHunting what?

@WillHunting Venn diagrams for nerds/hipsters?

@WillHunting Yep.

I guess you need area code.

@GustavoBandeira May be I will call you then.

+55 81 9720 1797

@GustavoBandeira give your adress,Id number,CPF...

@MeAndMath What did the guy from Pernambuco told you?

@GustavoBandeira the call was rejected.

@WillHunting So help out here!

@WillHunting listen

@JohnJunior It is. I have been trying to complete an exercise for past half an hour, have got nowhere. Must leave this place soon!!

@MeAndMath I guess you thought it was me. xD

@JayeshBadwaik The thing is you will not be able to do any serious stuff as long as you're here. @WillHunting

@JohnJunior Yup, so I am now going, see you guys later.

later

@GustavoBandeira yes...

@MeAndMath Haha

How would I discover it? Simplifying expressions in order to get your number?

@WillHunting So go and try and do some serious stuff and see how long you last.

@WillHunting And I didn't last...

@WillHunting Lookout!

@GustavoBandeira NOOOOOSSSSSAAAAAAAA

@GustavoBandeira Full access to Hunting's secrets.

@WillHunting yes

@WillHunting are you sure?

@WillHunting I believe that after you watch "A Brief History of Time" your "tragedy" will seem insignificant.

@WillHunting I'm not saying that.

John is a tragedy destroyer - He wants to deny tragedies for fun.

@WillHunting You have to watch it to understand what I mean :)

@GustavoBandeira Can't stop looking to that question

@MeAndMath A do simplify?

@GustavoBandeira y

Hoje eu vi uma do cara perguntando o que era base 18.

@WillHunting I'm trying,Mr.Hunting.

@GustavoBandeira I don't want to destroy tragedies I just want to put them in perspective.

Pra eu que achava que sabia de nada...

@JohnJunior Master Yoda taught us to never put tragedies in perspective, in his wise words: Eggplant for no four of you.

@GustavoBandeira I'm not sure if there is a translated version of the movie but it is nothing to joke about.

@WillHunting What would the dimension of the vector space $\mathbb R^{\mathbb N}$ be?

I have dimension defined based on the base of a vector space, but I don't know if the base for that space is finite,

And I only know about finitely generated vector spaces.

@WillHunting Yes.

@WillHunting Yes, I think so too.

@WillHunting But then, let $S=\{(u_n):u_{n+2}=u_{n+1}+u_n\}$

This is a subspace of $\bf R^N$

I want to find it's dimension.

@WillHunting I just think it has the same cardinality as $\bf R^N$

Each sequence is uniquely determined by the pair $(u_1,u_2)$

@MeAndMath Cê achou que eu tinha ligado - não era eu - mas você recusou a ligação. Porque cê me odeia? =/

@GustavoBandeira I don't hate you!My phone rejects unknown numbers.But I realized it wasn't you because you could'nt possibly know my number.But I don't hate you.I don't hate anyone.

You hate me. =/

Everybody does 8-(.

@GustavoBandeira I don't.Trust me

@JonasTeuwen Hi,Jonas.You suddenly appear...

You're no good

@MeAndMath Yes. Whenever the chat is about hostilites against me...

@GustavoBandeira No,no,no no!

@GustavoBandeira não sou hostil contigo.

Não, ele. xD

@GustavoBandeira Is that you... is that you in the picture?

You look like a drug lord.

A killing machine.

Creep.

@JonasTeuwen Yep. That's me. =)

I find Jonas very curious..

Cool!

@MeAndMath Why?

Drug lord FTW!

@WillHunting I would say "Trivial. QED.".

Kinda.

I have not done it in two months or so.

@JonasTeuwen Well,You claim to be stupid,when it's obvious,you are not.It's rare among mathematicians that kind of behaviour.And I think you are often Ironic...sometimes,too much.It's an intersting type of humour...But I don't see your expression or hear your voice...can't say.

My expression is very neutral. Some people call me a creep because of that.

But I am stupid.

@JonasTeuwen Hey, dawg.

Sup nigga.

Wigga.

@JonasTeuwen Need some help with $\bf R^N$

Is it's dimesion $\aleph_0$?

Jonas is sexy:everyone agrees on that.But about stupidity,I don't..

@MeAndMath So there are things to rectify!

@Gustavo Eu não te odeio,tá?

@JonasTeuwen Now, what is the dimesion of $S=\{(u_n)\in {\bf R^N}:u_{n+2}=u_{n+1}+u_n\; ;\;\forall n\}$?

@MeAndMath Odeia sim. =;

@WillHunting Kinda.

@PeterTamaroff It does not make sense.

@GustavoBandeira Não,não odeio.Que o faz pensar que sim?Se o odiasse não o levaria em cionta,não conversaria contigo...

Is it even a subspace?

@JonasTeuwen What doesn't make sense?

@JonasTeuwen It is.

I've checked it.

Oh.

So you want to know $0$ or $1$?

Other things are not possible unless you are considering covering dimension or small or large inductive dimension or crazy topological stuff.

@JonasTeuwen Huh? I want to nkow what is it's dimesion.

Oh, wait, it is a space of sequences.

So first question finite or infinite.

Caaardinalityyyy.

Let's just grab a beer.

Wadafuq.

@WillHunting I think it has dimesion 2!

@GustavoBandeira Oras!

$\langle \phi^n ,\phi^{-n}\rangle =S$

@WillHunting $1.618....$

@MeAndMath =)

The golden rrratio.

@PeterTamaroff isn't 1,618

@WillHunting That is bad and you should feel bad.

@JonasTeuwen é isso aí!

Vamos falar port pra enxer o saco...

Bleh, I have to go off to give a tennis class.

And the weather is horrible

Bye, silly people.

@PeterTamaroff Bye,Pedro!

XD

Naquele dia cê falou: "Brasileiro gosta de zuar" - eu subentendi que cê não gostava. xD

Vamos zuar!

não como os outros...

depende o que é zuar...

Jonas is so parsimonious with words...

O feeling dos caras

De onde?

OS LUSÍADAS

"Depende do que é zuar" - Apelou pra redefinição. xD

@GustavoBandeira DAQUI A POUCO VÃO NOS BANIR XD

@WillHunting How does that prove it is not larger than 2?

@MeAndMath Eu num vô receber um e-mail pedindo pra voltar.

@MeAndMath What?

@JonasTeuwen what what?

@WillHunting Hmm.

@MeAndMath Yeah.

@GustavoBandeira eu peço pra você voltar e você pede para mim! :D

@JonasTeuwen that you are parsimonious?

@MeAndMath Eu chamo todo mundo pra minha sala lá. Aí eu dou ban e kicko todo mund, só de zuá.

@GustavoBandeira hehehehe

@MeAndMath Ye.

@WillHunting Think I did...

@JonasTeuwen you are economic with words

@WillHunting Ah, nice. Sleepy.

@MeAndMath I don't like economics.

Give me all the money and then go fy.

Or so 8-)))).

you're niggard with words

you talk too little

I was asked is there a standard definition of triangle or are there several? I have only one geometry paper where triangle is defined one way.

@WillHunting MWAHAHAHA

@MeAndMath I talk too little? Sometimes I talk to much. I am never good 8-(((.

@JonasTeuwen you talk too much but in other meaning

Do explain you mysterious woman!

@JonasTeuwen I am not mysterious

@MeAndMath Mai tu qué porque qué, né? XD

Yes you are. You are. Tell me! When do I talk too much. Too much!!!

@WillHunting If I remember correctly, simply take three point that are not in the same line

@JonasTeuwen you are like an arrow..

@MeAndMath Explain.

I am not that thin :s.

Stop mocking my physique.

For I am the Hulk (in blue).

@JonasTeuwen a little accurate.you say too little but hit the target

I have to check

@WillHunting you will never see my face.Mwahahaha

@MeAndMath Cool!!

@GustavoBandeira que que eu quero?

@MeAndMath Que será?!

@GustavoBandeira o quê???

@MeAndMath Djivinha.

@GustavoBandeira eu não tenho bola de cristal...

Porra, isso é óbvio....

@GustavoBandeira o que,cacete

@WillHunting I think that is the only definition but on the other hand, there are different geometries like hyperbolic, Euclid so I was just wondering.

@MeAndMath Tarefa de casa: Faça uma redação de 30 linhas sobre o que você acha que deve ser.
