Threefold extremal curve germs with one non-Gorenstein point

Algebraic Geometry 2019-09-04 v3

Abstract

An extremal curve germ is the analytic germ of a threefold with terminal singularities along a reduced complete curve admitting a contraction whose fibers have dimension at most one. The aim of the present paper is to review the results concerning those contractions whose central fiber is irreducible and contains only one non-Gorenstein point.
