Title: Enumerative geometry of Lagrangian fibrations and monodromy

Abstract: We study the enumerative geometry of Lagrangian fibrations over affine bases. In many cases one can reduce enumerative problems on such spaces to the enumerative geometry of symplectic singularities for which there is a well developed theory. As an example, this talk will discuss the monodromy of the quantum differential equation for moduli spaces of sheaves on the cotangent bundle of an elliptic curve.
