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...
