Joint IAS/PU Symplectic Geometry Seminar
1:00pm|Simonyi Classroom (S-114)
Topic: Approximability for sSpaces of Lagrangian Submanifolds
Speaker: Octav Cornea
Affiliation: University of Montreal
Date: April 14, 2026
I will discuss a recent notion - called categorical approximability - that extends the property of precompactness of a metric space. This is applied to certain spaces of Lagrangian submanifolds endowed with the spectral metric, such as exact Lagrangians in cotangent disk bundles or equators on the 2-sphere. While approximable, these spaces are oten not precompact. The talk is based on recent joint work with Giovanni Amborsioni and Paul Biran.
