@Hippalectryon M2 l'année prochaine mais je ne sais pas vraiment quoi choisir.
May 28, 2017 20:58
@TedShifrin Lol
May 28, 2017 20:57
@Hippalectryon Des félicitations s'imposent!
May 28, 2017 20:56
@Hippalectryon ah ok. Tu vas choisir quoi ?
May 28, 2017 20:54
@Hippalectryon pourquoi?
May 28, 2017 20:53
Et des news de GrandDODOM (je ne sais plus très bien le pseudo)
May 28, 2017 20:53
@Hippalectryon Sinon comment se passe ton année ?
May 28, 2017 20:52
@Hippalectryon ;-)
May 28, 2017 20:50
Tu as son numéro ?@Hippalectryon
May 28, 2017 20:49
Good Bye
May 28, 2017 20:48
@Hippalectryon J'ai donné mon numéro à Astyx, pour organiser le repas avec Ted.
May 28, 2017 20:48
@Hippalectryon ça va! Tu seras toujours sur paris le 10juin ?
May 28, 2017 20:47
@TedShifrin Ah tant mieux, c'est plus agréable pour visiter.
May 28, 2017 20:47
@Hippalectryon ça va?!
May 28, 2017 20:46
@TedShifrin ça va mise à part la chaleur :p
May 28, 2017 20:45
@TedShifrin comment vas-tu ?
May 28, 2017 20:44
Hi @all
May 26, 2017 17:14
@TedShifrin hi Ted
May 26, 2017 17:01
limited why ?
May 26, 2017 17:01
@BalarkaSen do you know homology ?
May 26, 2017 17:00
@BalarkaSen i do not know $\pi_n$ for $n>1$ lol. I will learn it this summer I hope
May 26, 2017 16:58
arf you mean $\pi_n$ ?
May 26, 2017 16:58
@BalarkaSen yes
May 26, 2017 16:45
With algrebraic topology is it possible to use "basic" Homology ? Mayer-Vietoris? Excision theorem ?
May 26, 2017 16:44
I was reading the problem: Show that there doesn't exist a space $X$ such that $X\times X$ is homeomorphic to $S^{2}$, the 2-dimensional sphere.
May 26, 2017 16:39
pay grade ?!
May 26, 2017 16:37
@MikeMiller Hi Mike. Is there a ""link"" between a symmetric compact convex set with non-empty interior and a lattice $\mathcal{L}$ of $\Bbb{R}^n$?
May 22, 2017 18:01
it's not rude, it's a cordial peak (pic cordial pas sûr que j'ai bien traduit)
May 22, 2017 17:57
@TedShifrin funny that he didn't know that you speak french !
May 22, 2017 17:53
@Astyx Je n'ai pas reçu de message
May 22, 2017 17:51
@TedShifrin yeah but it's a bit difficult to understand reading on computer.
May 22, 2017 17:49
ou le Munkres
May 22, 2017 17:49
Je pense acheter le livre d'Hatcher car pas facile sur l'ordi
May 22, 2017 17:48
@TedShifrin je me suis découvert une """passion"" avec la topologie algébrique :)
May 22, 2017 17:47
confiance je ne sais pas, mais je suis pas de ceux qui ont peur :p
May 22, 2017 17:44
@Astyx Je te file mon numéro de téléphone ou adresse mel? Faudrait avoir celui de LeGrandDODOM et Hippa.
May 22, 2017 17:42
Je vais leur envoyer un commentaire sur leur profil mse :)
May 22, 2017 17:42
@TedShifrin D'accord. Il faut que j'en discute avec eux:)
May 22, 2017 17:35
@TedShifrin Vous venez toujours à Paris en juin ?
May 22, 2017 17:35
@TedShifrin Bonsoir
Apr 13, 2017 15:53
@DanielFischer hum, yeah, I was too optimistic :( thanks
Apr 13, 2017 15:49
@DanielFischer any finite subset ?!
Apr 13, 2017 15:46
@DanielFischer yep sorry it was stupid...
Apr 13, 2017 15:45
@DanielFischer hum no, say a open simply connected subset that contains the unit closed disc to a open simply connected subset that contains $F$
Apr 13, 2017 15:41
@DanielFischer complex numbers of module $1$
Apr 13, 2017 15:40
@DanielFischer $\Bbb{C}$
Apr 13, 2017 15:32
@DanielFischer Hi. Let $F$ be a finite set of $\Bbb{C}$ such that the line "between" two points does not pass through $0$. Can we find a bijective holomorphic function $f$ such that $f(G)=F$ where $G$ is a finite set of $\Bbb{U}$?
Apr 5, 2017 20:23
@Hippalectryon salut
Apr 5, 2017 20:19
@Astyx ça donne quoi en français ? ^^
Apr 5, 2017 20:07
I was trying to prove it using the facts I have.
