Geometry and Quantum Theory Seminar Speaker: Ben Gammage, Harvard University Title: Boundaries and duality for 3d gauge theories Abstract: 3d N=4 supersymmetric gauge theory has a pair of topological twists, the A-model and B-model, the latter of which is also known as Rozansky-Witten theory. Conjecturally, boundary conditions for these TFTs ought to admit descriptions in […]
Geometry and Quantum Theory Seminar Speaker: Dan Freed, Harvard University Title: Introduction to Factorization algebras
Geometry and Quantum Theory Seminar Speakers: Mayuko Yamashita, Kyoto University Title: Factorization algebras in TQFT Abstract: This is the first in the series of our working seminars on factorization algebras/homologies. This talk focuses on locally constant factorization algebras, which correspond to Topological QFTs. I first explain they are equivalent to algebras over E_n operads and […]
Geometry and Quantum Theory Seminar Speaker: Ahsan Khan Title: Perturbative Factorization Algebras Abstract: In physics the starting point in studying a QFT is to write down an appropriate action functional. My talk will aim to sketch how this connects with the framework of factorization algebras.
