[edit]The article should mention denting point, which is a stronger property than extremal point. --87.146.1.118 (talk) 00:34, 12 June 2012 (UTC)
"A theorem of Gerald Edgar states that, in a Banach space with the Radon–Nikodym property, a closed and bounded set is the closed convex hull of its extreme points." Is untrue. In any Banach space with more than one point a two-point set is closed and bounded, and not the convex hull of anything. Is it supposed to be that its closed convex hull is the closed convex hull of its extreme points? 109.157.202.249 (talk) 18:56, 24 February 2014 (UTC)
