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.
