The Summer School on "Enumerative Geometry and Geometric Representation Theory" will take place at the Centro Congressi Le Benedettine, in Pisa, from June 23 to June 29 and at the Department of Mathematics, University of Pisa, from June 30 to July 4, 2025. It can be seen as a second iteration of the 2021 IHÉS Summer School on "Enumerative Geometry, Physics and Representation Theory" organized by Neguţ, Sala, and Schiffmann. 

The school will offer six 5-hour lectures together with exercise/Q&A sessions and research groups. 

The school welcomes everybody but is primarily intended for Ph.D. students and young postdocs.

The Summer School will focus on the following main subjects: 

  • logarithmic and tropical geometry and relations to enumerative geometry
  • the geometry of the Hitchin moduli space
  • Donaldson-Thomas invariants, BPS states, and their categorification
  • Cohomological Hall algebras and their relation to enumerative geometry
  • Coulomb branches in geometry and representation theory


The registration procedure will open on November 1, 2024

We have limited funds. We may offer accommodations in shared rooms and partial travel support. If you need support, please let us know through the registration procedure.
Deadline for requesting support: February 15, 2025.
