## The Picard Group of the Moduli of Curves with Level Structures

### Mon., Feb. 1, 2010, 4:00pm, MATX 1100

Abstract:

The Picard group of an algebraic variety $X$ is the set of complex line
bundles over $X$. In this talk, we will describe the Picard groups of
certain finite covers of the moduli space of curves. The methods we use
combine ideas from algebraic geometry, finite group theory, and
algebraic/geometric topology.
