TITLE: Connes's unpublished manuscript on correspondences, anyone?
QUESTION [13 upvotes]: There exist unpublished notes on correspondences of von Neumann algebras due to Connes. This is often cited, but I've never seen a copy. It would be nice to have this, say, to maybe look further into the point of view discussed in his book Noncommutative geometry. Particularly, the stuff involving half-densities.
Does anyone have a scanned copy of this they wouldn't mind sending/posting a link to?
Thanks, in advance!

REPLY [6 votes]: Aren't you thinking of Popa's unpublished manuscript on Correspondences, available on his website:
