Speaker: Ishan Banerjee

Will give a Topology Seminar entitled:
Monodromy and vanishing cycles for curves in surfaces
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.
