On extremal contractions from threefolds to surfaces: the case of one non-Gorenstein point and non-singular base surface
Yuri G. Prokhorov
In this paper we study a local structure of extrmal contractions from threffolds with only terminal singularities onto a surface . If the surface is non…

On Extremal Contractions from Threefolds to Surfaces: the Case of One non-Gorenstein Point
Yuri G. Prokhorov
Let be an extremal contraction from a threefold with only terminal singularities to a surface. We study local analytic structure such contractions near degenerate…
