Braided tensor categories and the cobordism hypothesis Jordan, David
Description
In work with David Ben-Zvi and Adrien Brochier, we introduced a (would-be) 4-D topological field theory which relates to N=4 d=4 SYM in the same way that the Reshetikhin-Turaev 3-D theory relates to Chern-Simons theory. On surfaces it assigns certain explicit categories quantizing quasi-coherent sheaves on the character variety of the surface (along the Atiyah-Bott/ Goldman/Fock-Rosly Poisson bracket), and these in turn relate to many well-known constructions in quantum algebra. The parenthetical "would be" above means that, while the theory had an a priori definition on *surfaces* via factorization homology -- due to work of Ayala-Francis, Lurie, and Scheimbauer, these techniques do not apply to 3- and 4-manifolds. In this talk I'll explain work with Adrien Brochier and Noah Snyder, which constructs the 3-manifold invariants following the prescription of the cobordism hypothesis. This is in the spirit of Douglas-Schommer-Pries-Snyder's work on finite tensor categories -- but in the infinite setting -- and also echoes early ideas of Lurie and Walker. The resulting 3-manifold invariants quantize Lagrangians in the character variety of the boundary. They are not at all well-understood or computed explicitly in general, but they appear phenomenologically to relate to many emerging structures, such as quantum A-polyonomials, DAHA-Jones polynomials, and Khovanov-Rozansky knot homologies.

In work with David Ben-Zvi and Adrien Brochier, we introduced a (would-be) 4-D
topological field theory which relates to N=4 d=4 SYM in the same way that the Reshetikhin-Turaev
3-D theory relates to Chern-Simons theory. On surfaces it assigns certain explicit categories
quantizing quasi-coherent sheaves on the character variety of the surface (along the Atiyah-Bott/
Goldman/Fock-Rosly Poisson bracket), and these in turn relate to many well-known constructions
in quantum algebra.
The parenthetical "would be" above means that, while the theory had an a priori definition on
*surfaces* via factorization homology -- due to work of Ayala-Francis, Lurie, and Scheimbauer,
these techniques do not apply to 3- and 4-manifolds. In this talk I'll explain work with Adrien Brochier and Noah Snyder, which constructs the 3-manifold invariants following the prescription of
the cobordism hypothesis. This is in the spirit of Douglas-Schommer-Pries-Snyder's work on finite
tensor categories -- but in the infinite setting -- and also echoes early ideas of Lurie and Walker.
The resulting 3-manifold invariants quantize Lagrangians in the character variety of the boundary.

phenomenologically to relate to many emerging structures, such as quantum A-polyonomials,
DAHA-Jones polynomials, and Khovanov-Rozansky knot homologies.
