Singular Fibers of Some Minimal Abelian Fibrations Yoonjoo Kim (Columbia University)
Abstract: Let -> be a relative minimal model over a curve whose generic fiber is an - dimensional abelian variety. Then its special fiber , though not an abelian variety, admits a notion of an "abelian variety part". In this talk, I will classify these special fibers with an -dimensional abelian variety part. This generalizes Kodaira's classification of singular fibers in minimal elliptic surfaces, and Matsushita, Hwang, and Oguiso's classification of codimension 1 singular fibers in Lagrangian fibrations.
