Schaposnik %J Physics %D 1997 %I arXiv %R 10.1142/S0217732397002843 %X We show that, with the help of a general BRST symmetry, different theories in 3 dimensions can be connected through a fundamental topological field theory related to the classical limit of the Chern-Simons model. %U http://arxiv.org/abs/hep-th/9707210v1
