Quantum (Morava) K-theory Abstract:
Quantum cohomology is a well-known enumerative invariant of symplectic manifolds. For smooth projective varieties, quantum K-theory was defined around twenty years ago using the `virtual structure sheaf'. Recently we have constructed quantum K-theory, and quantum Morava K-theories, for general compact symplectic manifolds. We will describe something of this theory. This talk reports on joint work with Mohammed Abouzaid and Mark McLean.
4pm-5pm, room 383N Egor Shelukhin (University of Montreal),
Exact Lagrangians, fixed points, and flux Abstract: We describe the interrelation between the exactness of Lagrangian graphs, the strong Arnol'd conjecture, and the flux conjectures. In particular we answer a question of Lalonde-McDuff-Polterovich and make new progress on the \(C^0\) flux conjecture. This is joint work in progress with Marcelo Atallah.
