Sergey Cherkis (Arizona) “Exploded Geometry of Monopole Moduli Spaces”
–
Abstract: Computing the L2 cohomology of moduli spaces of monopoles and instantons is a challenging problem. It is significant in physics having an interpretations as counting the BPS states in quantum gauge theories, as well as in mathematics, manifesting itself in the geometric Langlands correspondence for complex surfaces. We propose a rather unconventional compactification of these moduli spaces … Read More
