Title: Index bounds in the Allen-Cahn construction

In the Allen-Cahn construction one constructs minimal surfaces as the
weak limit of level sets of a semilinear elliptic PDE, called the Allen-Cahn
equation. In this talk I will give a brief overview of the Allen-Cahn
theory, and then present my work relating the variational properties
of the solutions of the Allen-Cahn equation to the surface arising in
the limit. For example, the minimal surface inherits index bounds from
a sequence of unstable critical points; time permitting I will sketch a
proof of this.
