Topology Seminar - Ishan Banerjee
Ishan BanerjeeThe Ohio State UniversityTitleMonodromy and vanishing cycles for curves in an algebraic surfaceAbstractThis talk will be about the monodromy group associated to a family of algebraic curves in an algebraic surface as a subgroup of the mapping class group. I will start by surveying some older results in this area about the image of monodromy in the symplectic group. I will then discuss joint work with Nick Salter, where we describe the precise image of monodromy in the mapping class group in the special case of complete intersections.

Title
Monodromy and vanishing cycles for curves in an algebraic surface
Abstract
This talk will be about the monodromy group associated to a family of algebraic curves in an algebraic surface as a subgroup of the mapping class group. I will start by surveying some older results in this area about the image of monodromy in the symplectic group. I will then discuss joint work with Nick Salter, where we describe the precise image of monodromy in the mapping class group in the special case of complete intersections.
