SEMINARS, HARVARD-MIT ALGEBRAIC GEOMETRY
September 19, 2023 3:00 pmI spent most of my time here cycling (or is it biking?) and thinking about algebraic cycles from a homotopical viewpoint. I will speak about the latter. In joint work...

September 15, 2023 3:30 pmSince Floer's work in 1988, various Floer homologies have been constructed for closed 3-manifolds, knots, and sutured manifolds. In 2008, Kronheimer-Mrowka proposed a conjecture about isomorphisms among Floer homologies. In...

September 8, 2023 3:00 pmThe flag variety of rank r=(r_1,...,r_k) has points corresponding to collections of subspaces (V_1,..., V_k) with V_i of dimension r_i such that V_i is contained in V_{i+1}. It can be...

September 8, 2023 10:00 amEmergent symmetry can be generalized symmetry beyond (higher) group description and/or can be anomalous. I will describe a unified theory for generalized symmetry based on symmetry/topological-order correspondence. I will also...
