Next time: Spring 2019


This course is about 2D continuum random geometry. We will overview the recent progress in describing and studying natural families of random curves (SLE), random height functions (GFF) and random metrics (LQG), emphasising the intimate connections between these objects.


This course is about 2D continuum random geometry, a topic that has seen a rapid development over the past 20 years. We will discuss topics like the Schramm-Loewner evolution (a family of random curves), the Gaussian free field (a natural random height function), Brownian loop soups and Gaussian multiplicative chaos (a building-block for probabilistic models of 2D quantum gravity). An important part of this course is emphasising the strong connections between these objects and the interplay between probability theory and complex analysis.

Previous encounters with Brownian motion and complex analysis (to the level of Riemann mapping theorem) are very helpful.
