Abstract
We report progress in the computation and analysis of strong-coupling series of two- and three-dimensional models. We show that, through a combination of long strong-coupling series and judicious choice of observables, one can compute continuum quantities reliably and with a precision at least comparable with the best available Monte Carlo data.
