Gorenstein stable log surfaces with (K-X + Lambda)(2) = p(g)(X, Lambda)-1

摘要

In this paper, we will give a complete classification of Gorenstein stable log surfaces with where In particular, we classify Gorenstein stable surfaces with (K-X + Lambda)(2) = p(g)(X, Lambda) - 1 where p(g)(X, Lambda) - 1 h(0)(K-X + Lambda)(2,) In particular, we classify Gorenstein stable surfaces K-x(2) =p(g) - 1.
