Title pretalk: Introduction to twisted stable maps
Abstract pretalk: Twisted stable maps are a generalization of stable maps, which themselves are a generalization of stable curves. In this talk, I will introduce and give examples of all of these objects.
Title: A tour of twisted stable maps
Abstract: In this talk I will discuss the various lines of thinking which have resulted from a joint project with William C. Newman on the moduli space of twisted stable maps. This talk will range over several topics: from stable maps to gerbes to Brauer and Picard groups. The goal of all of this will be to analyze the structure of the moduli space of twisted stable maps and describe the integral Chow ring in some simple cases.
