摘要

An inverse Laplace transform on lattice spacing is introduced as a computational framework of the extrapolation of the strong coupling expansion to the scaling region.We apply the transform to the two-dimensional nonlinear O(N) model at N ≥ 3 and show that the approximation of the continuum limit of the susceptibility agrees with the existing theoretical and Monte Carlo data.
