Talk:Gromov's theorem on groups of polynomial growth

Latest comment: 1 year ago by 31.191.173.68 in topic Metric or convergence

NB current overlap with Growth rate (group theory).

I did a search for Gromov, nothing showed up

I dunno --delete it, join it CSTAR




Actually, I was planning saying something about proofs at some point, so maybe deletion isn't a good idea. CSTAR

Strange name

edit

It is really strange to give such a name for theorem, something should be specified, there are 100s of theorems which can be called Gromov's theorem, this can be only disamb. page... Tosha 00:50, 6 May 2004 (UTC)Reply

Maybe

edit

True... Maybe should have specifically called it Gromov's theorem on groups of polynomial growth. But probably most references to Gromov's theroem are to this theorem. But I don't at this point deletion of this page is a good idea CSTAR Wed May 5 20:17:56 CDT 2004

More theorems of Gromov would be excellent. But this one is famous (well, I knew it, as a non-specialist). Charles Matthews 05:42, 6 May 2004 (UTC)Reply

Found him...

edit

The Gromov in question appears to be Misha Gromov at IHES, the Institut des Hautes Études Scientifiques in Bures-sur-Yvette: http://www.ihes.fr/~gromov/ a.k.a. Michael Gromov —Preceding unsigned comment added by 213.253.40.226 (talkcontribs)

I put Mikhail (as the most standard one) Michael is french (?) and Misha is nickname Tosha 20:18, 13 Jun 2004 (UTC)

Metric or convergence

edit

In the proof he deals with non compact spaces, and there is no GH-metric in this case. (I'm not sure, he might use Lipschitz-Hausdorff distance??, but anyway this notion is not as popular now) In addition GH-metric is described in GH-convergence, so it should point there...

In fact there is a notion of GH-distance for "pointed" metric spaces, when they are not compact. As it often happens with fundamental groups though (which are defined for pointed topological spaces) the specification for of the point is often omitted. — Preceding unsigned comment added by 31.191.173.68 (talk) 17:10, 20 January 2023 (UTC)Reply
