Moon, Han-Bom
Mori's Program for $\overline{M}_{0,7}$ with Symmetric Divisors
We complete Mori's program with symmetric divisors for the moduli space of stable seven-pointed rational curves. We describe all birational models in terms of explicit blow-ups and blow-downs. We also give a moduli theoretic description of the first flip, which has not appeared in the literature.

Keywords:moduli of curves, minimal model program, Mori dream space

Scull, Laura
Equivariant Formality for Actions of Torus Groups
This paper contains a comparison of several definitions of equivariant formality for actions of torus groups. We develop and prove some relations between the definitions. Focusing on the case of the circle group, we use $S^1$-equivariant minimal models to give a number of examples of $S^1$-spaces illustrating the properties of the various definitions.
