Intermediate Jacobian fibration and wall crossing
Abstract: 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.
