This year, we will study the recent proof by Gunningham, Jordan, and Safronov of Witten’s finiteness conjecture for skein modules of closed oriented 3-manifolds. The school is designed for Master students, PhD students and researchers, younger and older. Participants are encouraged to choose a (not yet attributed) talk in the list. We are grateful to Renaud Detcherry, Benjamin Haioun, Francesco Costantino and Ramanujan Santharoubane for elaborating the program.
The event is supported by the GDR Tresses, the CIMI, the Mathematics Institute of Toulouse, the ERC project NEDAG.
The conference will be about the proof of the finiteness conjecture for skein modules by Gunningham-Jordan-Safronov. This conjecture of Witten asserts that for any oriented closed 3-manifold, the Q(A)-vector spaces spanned by isotopy classes of links in M modulo the Kauffman skein relations is finite dimensional. The Kauffman skein modules were first introduced by Przytycki and Turaev as a way to generalize the Kauffman bracket polynomial of knots and links in the 3-sphere . The conjecture is quite surprising as, by a result of Bullock, the skein module of M specialized at A = −1 gives back the SL(2,C)-character variety of M, which is often infinite dimensional. Witten allegedly formulated the conjecture based on the intuition that a dim 3 + 1 TQFT whose values on 3-manifolds are the skein modules should exist.
