There seem to be two distinct pages with the identical title "Lyusternik-Schnirelmann category" (in addition to other similar pages, such as "Lusternik-Schnirelmann category", etc). Why is this necessary? Katzmik 07:39, 3 May 2007 (UTC)[reply]

Definition[edit]

Should it not be defined so that we cover X by k+1 sets and $cat(S^{n})=1$ ? [1], [2],... 129.215.67.93 (talk) 14:16, 4 July 2012 (UTC)[reply]

Agreed. As it is now, one is induced to think that it is inconsistent with the definition in Ganea conjecture. Megaleoo (talk) 03:54, 13 September 2021 (UTC)[reply]

Category[edit]

I suppressed the term category since it can be confusing, see for instance Baire category of a space. — Preceding unsigned comment added by Xtquique (talk • contribs) 17:29, 3 November 2015 (UTC)[reply]

About the lower bound for the number of critical points[edit]

In the article is written that "It was, as originally defined for the case of X a manifold, the lower bound for the number of critical points that a real-valued function on X could possess". Shouldn't X be compact? Saung Tadashi (talk) 22:56, 6 January 2017 (UTC)[reply]
