School Colloquium——Integrability of Schramm-Loewner evolution and Liouville quantum gravity

2021-06-11 09:00-10:00 Online


Schramm-Loewner evolution (SLE) is a canonical family of random planar curves. Liouville quantum gravity (LQG) is a canonical theory for random surfaces. It appears that there are rich integrable structures in both SLE and LQG. Namely, many important observables admit exact expressions.  In this talk I will first give an overview of these two subjects, and then review two major resources of such integrability: conformal field theory and random planar maps decorated with statistical physics models. Finally I will present a recent work with Morris Ang that proves an integrable result for conformal loop ensemble, a collection of SLE type loops describing the scaling limits of many important 2D statistical physics models such as the Ising model. Our result is analogous to the DOZZ formula in Liouville conformal field theory. It is an example of a series of results that are proved by blending these two sources of integrability.
