==Problem vs. conjecture==

Line 55 ⟶ 58:

I wonder if it would make sense to add information on the contribution of Haagerup and Schulz on the relative version of the problem in II_1 factors.

==Hilbert space case solved?==

It is rumoured that Carl Cowen (Purdue) and Eva Gallardo-Gutiérrez (Madrid) have solved the Hilbert space case. The only evidence, so far, [https://twitter.com/RSME2013/status/294785891984101376/photo/1 is this picture]. We'll just have to wait for a preprint.

:Ah, but [http://cafematematico.com/2013/02/05/statement-from-cowen-and-gallardo/ there was a gap]. [[User:Hanche|Hanche]] ([[User talk:Hanche|talk]]) 14:20, 17 February 2013 (UTC)

==Second Bullet of "Known Special Cases" Needs Citation==

While the fact is obvious to experts in the field, talk of even any topological vector spaces that are not separable is extremely rare in the literature. I feel like the author had a precise source or straightforward inspired origin for the statement. The source making the remark or the inspiration for it should be cited accordingly.

== Solved for Hilbert spaces ==

Per Enflo just [https://arxiv.org/pdf/2305.15442.pdf published a proof], should this be added? — [[User:SourceIsOpen|SourceIsOpen]] ([[User talk:SourceIsOpen|talk]]) 13:16, 28 May 2023 (UTC)
