Title: Hassett-Keel Program in Genus Four
Abstract: The Hassett-Keel program aims to give modular interpretations of log canonical models for the moduli spaces of curves. The program, while relatively new, has attracted the attention of a number of researchers, and has rapidly become one of the most active areas of research concerning the moduli of curves. In the genus four case, we construct several of these models as GIT quotients of a single, elementary space.
