#### Monopole Floer homology and spectral geometry of hyperbolic three-manifolds

###### Francesco Lin (Columbia University)

Abstract: By studying the Seiberg-Witten equations, Kronheimer and Mrowka defined a package of invariants of three-manifolds called monopole Floer homology. In this talk, we discuss some interactions between this topological invariant and the spectral geometry of the Laplacian on the underlying Riemannian manifold, with the goal of understanding concrete examples of hyperbolic manifolds. This is joint work with Mike Lipnowski.
