Title: Stability conditions on K3 surfaces
Abstract: This is the first of two expository talks on stability
conditions. We give a leisurely introduction to Bridgeland stability
conditions, followed by a description of the space of stability conditions
on a K3 surface. An application to calculating the group of
autoequivalences of a K3 surface is outlined. The talk is based on a paper
of Bridgeland of the same title.

Title: Lyubeznik numbers
Abstract: Lyubeznik numbers are certain Bass numbers of local cohomology
modules associated with local rings containing a field. These numerical
invariants are known to have many interesting homological, geometric, and
topological properties and have been an active area of research. In this
talk, we plan to give a brief overview of these.
