Title:  Hassett-Keel Program in Genus Four
<br>
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.
