The gauge glass models are investigated from dynamical points of view. First, the gauge theory is extended to dynamical systems with both stochastic and deterministic dynamics. Some exact dynamical relations are derived. This provides an argument for the absense of re-entrant transition, which is also derived by the static theory. Next, the nonequilibrium relaxation analysis is applied to 2D systems. From the relaxation of order parameter, we find a typical divergence of the relaxation time at finite temperature in disordered regime, which reveals the stability of the KT phase against a weak disorder.
