comment recursion formula for odd holonomic function
Is this question too hard? I do not have any good idea yet.

comment Why must a reducible flat SU(2)-connection over a homology sphere be trivial?
$A^flat(M)/G(M)≅Hom(π_1(M),SU(2))/SU(2)$ is easy to prove. Just use geometric definition of connection.

I will check it. Thank you.

comment What is the definition of algebro-gemetric quotient?
what I am really interested is following: I have a group G, finitely presented. Consider R(G)=HOM(G,SL(2,C)), the space of all reps of G into SL(2,C). Then SL(2,C) acts on R(G) naturally, i.e. conjugation. So the usual quotient of this action is the space of orbits, which are all conjugacy classes of reps. Now the algebro-geometric quotient is not this. It is the character variety of G. Thanks.

OK. Thanks. So it is not a topological invariant?

Of Course. Thank you for your help.

I am a knot theory student. Try to learn some 4 manifold thing. So maybe this is a dummy question for expert. Thank you.
