Hi,

I'm looking at a problem requiring a 'weakening' (in a certain category
theoretic sense) of an automorphism of a lie group G. It seems to work
replacing Aut G with Diff_a G \in Diff G, which consists of diffeos homotopic
to automorphisms. Diff_a \neq Diff (apparently SO(3) is a counterexample).
What can we say about Diff_a G besides it being those path components of Diff
G containing an automorphism?

Thanks
