Intermediate Jacobian fibration and wall crossing

Speaker: Giulia Saccà

Location: Warren Weaver Hall 317

Date: Tuesday, April 9, 2019, 3:30 p.m.

Synopsis:

A few years ago with Laza and Voisin we constructed a hyperkahler
compactification of the intermediate Jacobian fibration associated to
a general cubic fourfold. In this talk I will first show how a HK
compactification J(X) exists for any smooth cubic fourfold X and then
discuss how the birational geometry of  the fibration is governed by
any extra algebraic cohomology classes on X.
