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...

  • On the existence of holomorphic curves in compact quotients of SL(2,C)

    AbstractIn my talk, I will report on recent joint work with I. Biswas, S. Dumitrescu and S. Heller showing the existence of holomorphic maps from a compact Riemann surface of genus g>1 into a quotient of SL(2,C) modulo a cocompact lattice which is generically injective. This gives an affirmative answer to a question raised by Huckleberry and Winkelmann and by Ghys. The proof uses ideas from har...
