SUMMARY:Fukaya category and gauge theory
DESCRIPTION:Geometry and Quantum Theory Seminar \nSpeaker: Saman Habibi Esfahani\, Harvard CMSA \nTitle: Fukaya category and gauge theory \nAbstract: After setting up some background\, I will discuss the Fukaya $A_\ infty$-category and several instances where it appears in gauge theory\, such as in the study of flat connections on Riemann surfaces\, holomorphic sections of some hyperkähler bundles\, and instantons and holomorphic curves in K3 surfaces. If time permits\, I will also outline potential applications of these ideas to the study of 3-manifolds and manifolds with special holonomy. \n  \n

SUMMARY:Algebraic approach to the bow construction
DESCRIPTION:Geometry and Quantum Theory Seminar \nSpeakers: Anadil Saeed Rao (Northeastern) and Vasily Krylov (CMSA/Harvard) \nTitle: Algebraic approach to the bow construction \nAbstract: Anadil will finish his part of the talk. Vasily will then explain how to understand moduli spaces of instantons on R^4\, monopoles on R^3\, and instantons on Taub-NUT spaces algebraically as so-called bow varieties. We will see how affine type A Nakajima quiver varieties and Slodowy slices arise as special cases of bow varieties. Time permitting\, we will also discuss applications to 3D mirror symmetry and Coulomb branches.

SUMMARY:Instantons on Taub-NUT space and Bow Construction
DESCRIPTION:Geometry and Quantum Theory Seminar \nSpeaker: Anadil Saeed Rao\, Northeastern University \nTitle: Instantons on Taub-NUT space and Bow Construction \nAbstract: In this talk I will discuss Yang-Mills Instantons in a very special geometric setting: the Taub-NUT space\, which itself is a Gravitational Instanton. In the first part of the talk I will review the essentials of gravitational instanton theory from the differential geometry/physics perspective and discuss the geometry of Taub-NUT space in detail. Then I will review the essentials of the ADHM-Nahm construction which describe Instantons and Monopoles in Euclidean R^4 and R^3 respectively. In the second part of my talk I will extend the ADHM-Nahm description to Instantons on Taub-NUT space and show how the ADHM-Nahm data may be presented in terms of combinatorial diagrams called Bows and their representations.

SUMMARY:Introduction to the probabilistic approach to Louville theory III
DESCRIPTION:Geometry and Quantum Theory Seminar \nSpeaker: Bowen Yang\, CMSA \nTitle: Introduction to the probabilistic approach to Louville theory III \nAbstract: I will continue with the construction of Liouville CFT from probabilistic methods\, following a review by Guillarmou\, Kupiainen\, and Rhodes (arXiv:2403.12780). The talk will emphasize technical aspects of Gaussian free fields (GFF) and contrast them with Brownian motion. The references is arXiv:2004.04720

SUMMARY:Factorization algebras in TQFT
DESCRIPTION:Geometry and Quantum Theory Seminar \nSpeakers: Mayuko Yamashita\, Kyoto University \nTitle: Factorization algebras in TQFT \nAbstract: 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 their variants. Then I define the factorization homology and discuss basic properties and examples. If time allows\, I also mention the connection with the cobordism hypothesis.
