Schedule

March 2nd

2:30-3:30    Hugo Duminil Copin :    Proving conformal invariance using discrete holomorphicity (Colloquium)
Watch on YouTube

The understanding of critical 2D statistical physics has undergone a revolution in the past two decades thanks to several breakthroughs. A celebrated discovery came with the introduction of SLE by Oded Schramm. This process describes the scaling limit of interfaces of models at criticality and therefore led to an important machinery sheding a completely new light on 2D statistical physics.
But another tool, called discrete holomorphicity, was introduced at the same time and enabled the proof of conformal invariance for very important 2D lattice models. This tool originated in graph theory before being used in statistical physics to prove conformal invariance of the dimer and the planar Ising models.
In this talk, we will review the use of discrete holomorphicity in 2D statistical physics.

4:00-5:30    Ori Gurel Gurevich :    On Smirnov's proof of conformal invariance of critical percolation (Basic Notions)    Watch on YouTube

March 3rd

9:00-10:00    Hugo Duminil Copin :    Discrete holomorphicity and boundary value problems
In this talk, we will describe the notion of discrete holomorphicity in more details. In particular, we will explain how solutions to discrete value problems can be proved to converge to their continuum counterparts. This key fact will be instrumental in the proofs of conformal invariance.

10:15-11:15    Hugo Duminil Copin :    Applications of discrete holomorphicity to the proofs of conformal invariance of the dimer and Ising models
In this talk, we apply discrete holomorphicity to the proof of conformal invariance of the dimer and Ising models.
