Loop space: De Rham cohomology
up vote 8 down vote favorite
How to calculate the DeRham cohomology of the free loop space $LM= C^\infty(S^1,M)$ as a Frechet manifold?.
Edit: It will be enough for me to know: When $H^1_{DR}(LM)$ is not $\{0\}$.
Bounty is ending within 5 hours.

Super combinator
From HaskellWiki
A super combinator is either a constant, or a Combinator which contains only super combinators as subexpressions.
This definition is bewildering until you realize that a Combinator can have non-Combinator internal subexpressions. A super combinator is "internally pure" (every internal ... | {"url":"http://www.haskell.org/haskellwiki/index.php?title=Super_combinator&oldid=21702","timestamp":"2014-04-16T14:38:43Z","content_type":null,"content_length":"14710","record_id":"<urn:uuid:620070c3-1c76-499b-97fd-86c6af0eeffb>","cc-path":"CC-MAIN-2014-15/segments/1397609523429.20/warc/CC-MAIN-20140416005203-00193-ip... |
