Eduardo Gonzalez- Quantum Cohomology, Seidel Elements, Shift Operators & Coulomb Branches

Explore a comprehensive lecture on quantum cohomology, Seidel elements, shift operators, and Coulomb branches presented by Eduardo Gonzalez from the University of Massachusetts. Delve into joint research with D. Pomerleano and C. Y. Mak, focusing on the construction of an action of the semi-infinite equivariant cohomology of the based loop group of a Lie group G on the equivariant symplectic homology of a symplectic G-manifold. Begin with an introduction to classic results on Seidel/shift operators for closed symplectic manifolds, providing a solid foundation for understanding the more advanced concepts discussed throughout the 44-minute talk.
