Abstract
We study lattice g0phi4 field theory for all g0 and fixed renormalized mass M in one and two dimensions using Monte Carlo techniques. We calculate the dimensionless renormalized coupling constant is the dimension of space--time, at fixed small values of the lattice spacing a for various g0 and lattice sizes. Our results are in quantitative agreement with the analyses of high temperature and strong coupling series which rely on extrapolation from large to small lattice spacing.
