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.

  • 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...

  • Intersection of holomorphic curves with generic hypersurfaces

    About the SeminarThis seminar centered loosely around algebraic dynamics, complex dynamics, and related topics. We meet weekly for a 90-minute talk, with the first 30 minutes aiming towards non-experts and graduate students. After the talk we will have 30 minutes of informal discussion.More information about the seminar can be found at:https://ywfan-math.github.io/ADCD.html AbstractLet f be hol...
