| Feb 18, 2013 at 16:53 | comment | added | Alain Valette | $Diff(M)$ is the group of diffeomorphisms, and the question is how properties of $Diff(M)$ reflect in topological properties of $M$. | |
| Feb 18, 2013 at 16:29 | comment | added | Mariano Suárez-Álvarez | What is Diff(M) here? The notation is usually used to denote the group of diffeomorphisms, but then Stephan's comment is weird. | |
| Feb 18, 2013 at 15:44 | comment | added | Koushik | i don't see why Diff(M) should be a subsheaf of C(M). | |
| Feb 18, 2013 at 15:39 | comment | added | Koushik | i am asking both way | |
| Feb 18, 2013 at 15:13 | comment | added | Stephan Müller | I guess the question is a bit vague. Is Diff(M) the subsheaf of C(M) of smooth functions on M? Clearly, if Diff(M) has non-trivial idempotents, so has C(M). Are you asking for the converse? | |
