High Energy Theory Seminar

I will discuss the contribution of higher-genus surfaces in JT gravity. In work with Saad and Shenker, we use Mirzakhani's recursion and work of Eynard and Orantin to show that these contributions exactly coincide with the genus expansion of a particular double-scaled matrix integral. I will explain this and then discuss a JT gravity interpretation of nonperturbative effects in this matrix integral.
