SUMMARY:The categorical 't Hooft expansion
DESCRIPTION:Quantum Field Theory and Physical Mathematics Seminar \nSpeaker: Davide Gaiotto (Perimeter Institute) \nTitle: The categorical ‘t Hooft expansion \nAbstract: The ‘t Hooft expansion is the key structure underlying dualities between gauge theories of large matrices and string theories. I will review categorical aspects of the ‘t Hooft expansion\, matching the formal deformation space of certain “fundamental modifications” of the gauge theory to the formal deformation space of a category of boundary conditions (“D-branes”) for a 2d dg-TFT\, to be identified with the world-volume theory for the string theory. I will illustrate this by reviewing the holographic description of matrix models.
