Is this sequence named for Erling Folner (possibly Erling Følner) who was a mathematician in the 50s? dbenbenn | talk 23:54, 23 Jan 2005 (UTC)

Yes, see [1], reference 8. dbenbenn | talk 04:11, 16 March 2006 (UTC)[reply]

Where is second countability used in the proof of amenability in the generalized case? --Sabalka (talk) 02:41, 5 March 2008 (UTC)[reply]



Can somebody please show me where in Følner's paper (the only reference in the article...) the proof in "Proof of amenability"-the one with ultralimits-can be found? Følner talks about Banach mean values (means) and functionals, which in a way is a completely different language to "measures on G". Where does this proof come from? 131.217.255.204 (talk) 02:55, 13 May 2013 (UTC)[reply]
