Threefold extremal contractions of type (IA)
Let be a germ of a threefold with terminal singularities along an irreducible reduced complete curve with a contraction such that and is ample. Assume that a general member meets only at one point , and furthermore assume that is Du Val of type A if index . We classify all such germs in terms of a general member containing .
