We examine the possibility of fermion mass generation in 2+1–dimensional gauge theory from the current algebra point of view. In our approach the critical behavior is governed by the fluctuations of… (More)

We investigate non-perturbative features of a planar Chern-Simons gauge theory modeling the long-distance physics of quantum Hall systems, including a finite gapM for excitations. By formulating the… (More)

We construct a lattice model of compact (2+1)-dimensional Maxwell-Chern-Simons theory, starting from its formulation in terms of gauge invariant quantities proposed by Deser and Jackiw. We thereby… (More)
