Title:
Branes on Moduli Spaces of Sheaves
Speaker:
Abstract:
Branes are special submanifolds of hyperkahler manifolds that play an important role in string theory, particularly in the Kapustin-Witten approach to the geometric Langlands program, but which also are of intrinsic geometric interest. More precisely, a brane is a submanifold of a hyperkahler manifold which is either complex of Lagrangian with respect to each of the three complex structures or Kahler forms composing the hyperkahler structure. Branes on moduli spaces of Higgs bundles have been largely studied by many authors; in this talk, I will summarize recent work done in collaboration with Franco, Marchesi, and Menet on the construction of different types of branes on moduli spaces of framed sheaves on the projective plane, on moduli spaces of sheaves on K3 and abelian surfaces, and on moduli spaces of Higgs bundles via Nahm transform.
