S4F1 Graduate Seminar in Probability:

Schramm-Loewner Evolution


Time: Wednesday 14st

Room:  SR 0.007

 

Description:

Schramm-Loewner Evolution (or SLE) is the unique one-parameter family of random simple curves in the plane that are conformally invariant: If \(\Phi:D\to D'\) is a conformal mapping between two domains \(D,D'\subset\mathbb{R}^2\), then the law of the image of an SLE in \(D\) coincides with the law of the SLE in \(D'\).

This concept has received a lot of attention in the last decade and SLE is at the heart of some of the most fascinating recent developments in probability and mathematical physics.

On the one hand, the mathematics involved is a beautiful interplay of probability and complex analysis. On the other hand, these processes have opened to the door to a rigorous mathematical description of the scaling limits of many models from statistical mechanics at criticality in two dimensions. These include e.g. percolation, the Ising model and loop erased random walks.

In the seminar we will introduce the concept of Schramm-Loewner Evolution, study properties of the SLE processes and sketch the connection to scaling limits of lattice models.
