Monodromy of algebraic curves in an algebraic surface
Title: Monodromy of algebraic curves in an algebraic surface
Speaker: Ishan Banerjee (OSU)
Abstract: In this talk I will survey what is known about the monodromy group of all smooth algebraic curves embedded in an algebraic surface X of a fixed divisor class |D|. I will discuss how pi_1X can present obstructions to the monodromy group being finite index in the mapping class group. If time permits, I will discuss how the image of the monodromy group in quotients of the mapping class group by Johnson subgroups are 'as big as possible' assuming that D is sufficiently ample.
