  • Sebastian Haney (Columbia University) : Open enumerative mirror symmetry for lines in the mirror quintic

    One of the earliest achievements of mirror symmetry was the prediction of genus zero Gromov-Witten invariants for the quintic threefold in terms...

The Asymptotic Mean Action and the Asymptotic Linking Number For Pseudo-Rotations
Abror Pirnapasov
1:00pm|Simonyi 101 and Remote Access

By the Birkhoff Ergodic Theorem, the asymptotic mean action of an area-preserving map is defined almost everywhere. Bramham and Zhang asked whether, if a map is a pseudo-rotation, its asymptotic mean action is defined everywhere and is constant. In...

New Invariants for Hamiltonian Isotopy Classes of Monotone Lagrangian Torus Fibers
Felix Schlenk
9:15am|Remote Access

Based on the exotic Lagrangian tori constructed in CP$^2$ by Vianna and Galkin-Mikhalkin, we construct for each Markov triple three monotone Lagrangian tori in the 4-ball, and for triples with distinct entries show that these tori lie in different...
