Abstract

We calculate the first two non-zero terms in the perturbative expansion of the additive and multiplicative renormalizations of the topological susceptibility, χ, in the 2D CPN−1 model, when a density of topological charge is defined as a local operator on the lattice. We compare our results with some direct determinations, by Monte Carlo techniques.
