## Higgs Bundles, Spectral Covers, and their Characteristic Classes

##### Abstract:

A ``Higgs bundle" is essentially a family of matrices, and if you try to diagonalize one you get a "spectral cover." They arise in the study of moduli of vector bundles. I will introduce Higgs bundles and spectral covers, and then I will describe their cohomological invariants.
