Abstract

In [Böh] a structure theorem for Gorenstein algebras in codimension 2 was obtained. In the first part of this article we give a geometric application and prove a structure theorem for good birational canonical projections of regular surfaces of general type with to (Theorem 1.6). In the second part we show how this can be used to analyze the moduli space of canonical surfaces with , and (Theorem 2.4).
