DESCRIPTION:Title: <a href="https://researchseminars.org/talk/BUGeom/25/">
 Kapustin—Witten TQFT on 3-manifolds and derived skein modules</a>\nby Pa
 vel Safronov (University of Edinburgh) as part of Boston University Geomet
 ry/Physics Seminar\n\nLecture held in Zoom meeting ID: 953 4652 9200.\n\nA
 bstract\nKapustin and Witten have proposed that there is a 4-dimensional T
 QFT underlying the geometric Langlands program and have described it as a 
 topological twist of the 4-dimensional maximally supersymmetric Yang—Mil
 ls theory. In this talk I will discuss some mathematically-rigorous ways t
 o define the space of states for 3-manifolds\, relating it to skein module
 s and complexified instanton Floer homology of Abouzaid—Manolescu. I wil
 l also comment on the possible extension of the geometric Langlands dualit
 y to 3-manifolds. This is based on work in progress with D. Jordan and S. 
 Gunningham.\n
