A tour of categorical symmetry
Title: A tour of categorical symmetry Abstract: I will discuss some perspectives on symmetry coming from the study of topological defects in quantum field theory. I will argue that we […]

A mirror theorem for GLSMs
Abstract: A gauged linear sigma model (GLSM) consists roughly of a complex vector space V, a group G acting on V, a character \theta of G, and a G-invariant function w […]

Title: On counting algebraically defined graphs Abstract: For many classes of graphs that arise naturally in discrete geometry (for example intersection graphs of segments or disks in the plane), the edges of […]
Derived projectivizations of two-term complexes
Abstract: For a given two-term complex of vector bundles on a derived scheme (or stack), there are three natural ways to define its “derived projectivizations”: (i) as the derived base-change of […]
Some remarks on contact Calabi-Yau 7-manifolds
Abstract: In geometry and physics it has proved useful to relate G2 and Calabi-Yau geometry via circle bundles. Contact Calabi-Yau 7-manifolds are, in the simplest cases, such circle bundles over Calabi-Yau 3-orbifolds. […]
Knot homology and sheaves on the Hilbert scheme of points on the plane
Speaker: Alexei Oblomkov (University of Massachusetts) Title: Knot homology and sheaves on the Hilbert scheme of points on the plane Abstract: The knot homology (defined by Khovavov, Rozansky) provide us […]
