Knot contact homology, Chern-Simons theory and topological string theory by Tobias Ekholm (Uppsala University)
An introduction to the basic concepts from contact topology. In particular we will define knot contact homology which is the Legendrian differential graded algebra of the unit conormal lift of a knot. We will mention how a non-commutative version of the Legendrian DGA with a pair-of-pants like product actually determines the knot class completely. We also introduce basic results from physics relating topological string and gauge theories. We show how - after large N-transition - the augmentation variety of knot contact homology determines the Gromov-Witten disk potential of the Lagrangian conormal after large N transition. We will outline a program for calculating higher genus amplitudes via a generalization of Legendrian contact homology, Legendrian Symplectic Field Theory. The program in particular involves topological recursion at infinity which determines higher genus amplitudes from refined disk amplitudes at infinity.
Introduction to BV-BFV quantization by Nicolai Reshetikhin (UC Berkeley)
A brief recollection of facts about graded supermanifolds and BV integrals. Then the basic framework for BV_BFV quantization of gauge theories on space time with boundary will be introduced. After this we will focus on an example of topological quantum filed theory on cell complexes: the discrete abelian BF theory. If time permits we will also discuss perturbative quantization of Poisson sigma model. This session is a sequel to last year’s masterclass on BV quantization.
