SUMMARY:Boundedness for K-trivial varieties with fibrations
DESCRIPTION:Differential Geometry and Physics Seminar  \nSpeaker: François Greer\, MSU \nTitle: Boundedness for K-trivial varieties with fibrations \nAbstract: According to the Beauville-Bogomolov decomposition theorem\, any smooth K-trivial variety admits a finite cover by a product of (1) abelian varieties\, (2) strict Calabi-Yau varieties\, and (3) irreducible holomorphic symplectic varieties (IHSV). In a fixed dimension\, all abelian varieties are diffeomorphic\, and indeed deformation equivalent through non-algebraic complex tori. The corresponding question remains largely open for cases (2) and (3). If we assume that a variety of class (2) or (3) admits a non-trivial fibration structure\, then much more can be shown. In particular\, fibered Calabi-Yau threefolds have bounded moduli problem\, and IHSV of a fixed dimension with a Lagrangian fibration have bounded moduli. This is based on joint work with Engel\, Filipazzi\, Mauri\, and Svaldi. \n\n  \n
