Gauge vector and gravity models are studied in three-dimensional space-time, where novel, gauge invariant, P and T odd terms of topological origin give rise to masses for the gauge fields. In the vector case, the massless Maxwell excitation, which is spinless, becomes massive with spin 1. When inter

In pseudo-Euclidean metrics the Chern Simons gauge theory in the infrared region is found to be associated with dissipative dynamics. In the infrared limit the Lagrangian of (2+1)dimensional pseudo-euclidean topologically massive electrodynamics has indeed the same form as the Lagrangian of the damp
