Abstract
In order to understand how gauge fixing can be affected on the lattice, we first study a simple model of pure Yang-mills theory on a cylindrical spacetime [SU(N) on S 1 × R] where the gauge fixed space is explicitly displayed. On the way, we find that different gauge fixing procedures lead to different Hamiltonians and spectra, which however coincide under a shift of states. The lattice version of the model is then compared. 1.
