Holomorphic spheres and disks in symplectic manifolds

2025-01-13

Speaker: Luis Diogo (Univ. Uppsala, Sweden)

(Pseudo-)holomorphic curves have had a central role in symplectic geometry since their introduction by Gromov in 1985. We will review some applications of this tool, and present current work relating holomorphic spheres and holomorphic disks with their boundaries on Lagrangian submanifolds....

Isometries and other symmetries of positive cones in operator algebras

2025-01-14

Speaker: Lajos Molnar (University of Szeged, Hungary)

The classical Banach-Stone theorem describes the general form of all surjective linear isometries between the spaces of all continuous scalar-valued functions on compact Hausdorff spaces. It has a substantial generalization in the noncommutative setting obtained by Kadison in which he...

Schubert calculus, Virasoro constraints and vertex operators

2025-01-20

Speaker: Miguel Moreira (MIT, USA)

The Virasoro constraints are one of the major open problems in enumerative geometry, originally in Gromov-Witten theory, but more recently also for moduli spaces of sheaves or representations of quivers. The latter have connections to vertex algebras and wall-crossing. In this...
