Im looking for a good resource that clearly explains the problem of Gribov ambiguity. In particular, I want to know
1. Why the problem only arises for non-abelian theories
2. Why restricting the functional integration to field configurations where the Faddeev-popov determinant is postive solves the problem for perturbative theories
3. Why this doesn't work for non-perturbative theories
Thanks in advance
