Hilbert schemes, sheaves & representations

19 Febbraio 2013
2013 Workshop of the vector bundles on algebraic curves group

June 17-21, 2013 - SISSA

Hilbert schemes of points are a traditional field of interest for algebraic geometers. Work by Nakajima and others established a relation between their geometry and the representation theory of Heisenberg-Clifford algebras.

More recent research connected Hilbert schemes with other infinite-dimensional algebras, such as Cherednik algebras, quantum Heisenberg algebras, Kac-Moody algebras, and so on. This conference aimed at providing an updated survey of the state of the art in this area of research in its various aspects.

June 17-21, 2013


  • categorification of the (quantized) Heisenberg algebra
  • Cherednik algebras, W-algebras
  • Ding-Iohara algebras, shuffle algebras
  • moduli spaces of instantons and framed sheaves
  • instanton counting, Alday-Gaiotto-Tachikawa conjecture
  • instanton counting with surface operators, moduli spaces of parabolic framed sheaves
  • moduli spaces of quiver representations, wall-crossing formulas
