Explore the intricate relationship between algebraic geometry and symplectic topology in this 22-minute conference talk from the IAS/Princeton/Montreal/Paris/Tel-Aviv Symplectic Geometry Zoominar. Discover a novel class of numerical invariants constructed from matrix factorizations that serve as mirror counterparts to open Gromov–Witten invariants. Learn how matrix factorizations function as algebraic objects that correspond to Lagrangian submanifolds in Fano manifolds under mirror symmetry. Delve into the non-Archimedean framework essential for defining these invariants and examine key results regarding their structural properties. Gain insights into cutting-edge research in symplectic geometry and mirror symmetry through this collaborative work with J. Solomon, presented by May Sela from The Hebrew University of Jerusalem.
