Abstract

We apply the perturbative variational approximation scheme of Bessis and Villani to Z(2) gauge theory on a lattice in 2 + 1 and 3 + 1 dimensions and to a truncated version of SU(2) gauge theory in 3 + 1 dimensions. We find that the BV scheme tends to distinguish between first- and second-order transition already in the first approximant.
