Abstract :
The seminal works of Kapustin—Witten and Gaiotto—Witten propose that various "Langlands type" correspondences can be interpreted as S-duality for a family of 4D gauge theories. Beginning with an exposition of relative Langlands duality in the sense of Ben-Zvi—Sakellaridis--Venkatesh along these lines, we discuss a program in which we explore and realize some features of the hypothetical Langlands TQFT in the Dolbeault twist. This talk involves joint work in progress with Emilio Franco, Enya Hsiao, and Mengxue Yang.
