Description
We present an explicit superspace calculation of the quantum corrections, up to four-loop order in perturbation theory, for the N=2 non-linear σ-model in two-dimensions. At the four-loop level we find a non-zero contribution to the β-function which does not vanish on a Ricci-flat Kaehler manifold. We discuss the relevance of this result in connection with superstring compactification. (orig.)
