- Gribov_ambiguity abstract "In gauge theory, especially in non-abelian gauge theories, global problems at gauge fixing are often encountered. Gauge fixing means choosing a representative from each gauge orbit. The space of representatives is a submanifold and represents the gauge fixing condition. Ideally, every gauge orbit will intersect this submanifold once and only once. Unfortunately, this is often impossible globally for non-abelian gauge theories because of topological obstructions and the best that can be done is make this condition true locally. A gauge fixing submanifold may not intersect a gauge orbit at all or it may intersect it more than once. This is called a Gribov ambiguity (named after Vladimir Gribov).Gribov ambiguities lead to a nonperturbative failure of the BRST symmetry, among other things.A way to resolve the problem of Gribov ambiguity is to restrict the relevant functional integrals to a single Gribov region whose boundary is called a Gribov horizon.See also the original paper of Gribov, Heinzl's paper with a quantum-mechanical toy example, and the second slide of Kondo's presentation.".
