    "abstract": "We consider in general terms dynamical systems with finite-dimensional,\nnon-simply connected configuration-spaces. The fundamental group is assumed to\nbe finite. We analyze in full detail those ambiguities in the quantization\nprocedure that arise from the non-simply connectedness of the classical\nconfiguration space. We define the quantum theory on the universal cover but\nrestrict the algebra of observables $\\O$ to the commutant of the algebra\ngenerated by deck-transformations. We apply standard superselection principles\nand construct the corresponding sectors. We emphasize the relevance of all\nsectors and not just the abelian ones.",
