# Group actions and stability on elliptic surfaces

DIFFERENTIAL GEOMETRY

##### Speaker:

Jason Lo *- CSUN*

There are two natural group actions on the Bridgeland stability manifold of a triangulated category: a left action by the group of autoequivalences, and a right action by the universal covering space of $\mathrm{GL}^+(2,\mathbb{R})$.

This work is partly motivated by an attempt to understand equivalences of triangulated categories in representation theory and algebraic geometry at the same time.
