AG : John Lesieutre (Pennsylvania State University) : Volume near the pseudoeffective boundary

14 octobre / 13:30 - 14:30

Abstract: Suppose that X is a projective variety and that L is a line bundle on X. The volume of L is a measure of the asymptotic growth rate of the number of sections of tensor powers of L. After providing some background on this invariant, I will explain some pathological behaviors of the volume function which have origins in the dynamics of birational automorphisms of a certain Calabi-Yau threefold X.
