Gribov ambiguities and the fundamental domain

Abstract

This lecture is dedicated to the memory of Vladimir Gribov. We discuss the procedure of complete gauge fixing to avoid Gribov copies, as well as results for the low-lying glueball spectrum in intermediate volumes for the torus and for the sphere that became available recently.
