Some issues about the Gribov and the modular re- gions are shortly discussed. The Gribov copies of the vacuum in 3D QCD in the Coulomb gauge are described. An interesting implication of the presence of Gribov copies is briefy pointed out.15 pages, no figures; references added, clarifying comments includedHigh Energy Physics - TheoryGeneral Relativity and Quantum CosmologyMathematical Physicstext
