P. 623–652.
Prokhorov Y., Mori S.
Let (X,C) be a germ of a threefold X with terminal singularities along an irreducible reduced complete curve C with a contraction f:(X,C)→(Z,o) such that C=f−1(o)red and −KX is ample. Assume that (X,C) contains a point of type (IIA). This paper continues our study of such germs containing a point of type (IIA) started in our previous paper.
