INDUCED CHERN-SIMONS TERM IN 3-DIMENSIONAL SPACE AT HIGH-TEMPERATURE

Perturbative calculations of the high temperature ground-state axial v ector current of fermion fields coupled to gauge fields lead to an app earance of an additional anomalous Chern-Simons topological mass term in three-dimensional effective action. In Abelian case contributions c ome only from the vacuum polarization graph, and in non-Abelian case c ontributions come from the vacuum polarization graph and the two trian gle graphs.
