Abstract
We evaluate exactly both the nonrelativistic and relativistic fermion deter minant in 2+1 dimensions in a constant background field at finite temperatu re. The effect of finite chemical potential is also considered. In both cas es, the systems are decoupled into an infinite number of 1+1 fermions by Fo urier transformation in the beta -variable. The total effective actions dem onstrate nonextensiveness in the beta -dimension.
