Abstract

We show how to treat boundary divergences in heterotic string theory covariantly and unambiguously. The method applies even to theories with nonvanishing tadpoles; in this case the Fischler-Susskind mechanismsuffices to ensure unambiguous amplitudes. No splitting or projection of supermoduli space is needed.
