Stable (parabolic) holomorphic vector bundles over complex curves and instanton Floer homology

Abstract

Stable holomorphic bundles are objects in algebraic geometry which have been studied by many people. Instanton Floer homology is an invariant of 3-manifolds, which has been used to solve many problems in the low dimensional topology. It turns out the two things are closely related: knowledge on the moduli space of stable bundles can help the calculation of Instanton Floer homology. In this talk, I will explain this relationship and its generalization to stable parabolic bundles. This is joint work with Boyu Zhang.

Derived categories of moduli of parabolic bundles on a projective line | BIMSA AG Seminar
AbstractThere has been a lot of work done recently in the study of the bounded derived categories ofmoduli spaces of parabolic bundles on curves. Let C be a curve of genus at least two, and let L bea line bundle of odd degree on it. l was observed some time ago that the motive of the modulispace of rank 2 stable vector bundles on C with determinant L decomposes into motives ofsymmetric powers o...
