Hugo Duminil Copin - Rotational invariance of planar random cluster models... and beyond?

Recorded 22 May 2024. Hugo Duminil-Copin of The University of Geneva presents "Rotational invariance of planar random cluster models... and beyond?" at IPAM's Vertex Models: Algebraic and Probabilistic Aspects of Universality Workshop.
Abstract: Several years ago, Grimmett and Manolescu introduced an innovative technique that proved instrumental in establishing the universality of critical exponents within planar bond Bernoulli percolation models. This groundbreaking strategy, rooted in the star-triangle transformation, later found application in the broader realm of random cluster models. Notably, it was employed to demonstrate the rotation invariance of the model. In this presentation, we delve into the exploration of new avenues enabled by rotation invariance, aiming to extract fresh insights into critical random cluster models on Z^2.
