Joint Harvard-CUHK-YMSC Differential Geometry Seminar: Quantum cohomology as a deformation of symplectic cohomology

SEMINARS: DIFFERENTIAL GEOMETRY

When: November 24, 2021
4:00 pm - 5:00 pm
Where: Virtually
Speaker: Nick Sheridan - School of Mathematics, University of Edinburgh

Let X be a compact symplectic manifold, and D a normal crossings symplectic divisor in X. We give a criterion under which the quantum cohomology of X is the cohomology of a natural deformation of the symplectic cochain complex of X D. The criterion can be thought of in terms of the Kodaira dimension of X (which should be non-positive), and the log Kodaira dimension of X D (which should be non-negative). We will discuss applications to mirror symmetry. This is joint work with Strom Borman and Umut Varolgunes.
