Quantifying Lagrangian rigidity

20.10.2022 16:15

Lagrangian submanifolds are ubiquitous in symplectic geometry, and Lagrangian intersection or isotopy results underlie much of symplectic rigidity. On the other hand, given enough space, intersections can be eliminated and Lagrangians unknotted.
We will survey results in quantitative symplectic topology, which aims to address questions of space. This will start with Gromov's nonsqueezing theorem, and, time permitting, mention some joint works with Ely Kerman, Emmanuel Opshtein and Jun Zhang on the possibilities for squeezing Lagrangians.
