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.
