DESCRIPTION:Speakers: Rémy Mahfouf\n\nIn this talk we will present the fo
rmalism of s-embeddings of weighted abstract planar graphs carrying the Is
ing model\, introduced recently by Chelkak. In that setup and under rather
mild geometric assumptions\, we derive usual crossing estimates for the F
K Ising model that indentifies some critical and near critical regime for
a given abstract graph. We finish by presenting new convergence statements
enlightening the rather unexpected link between the Ising model and the L
orentz geometry discovered by Chelkak\, which leads to reimebed planar gra
phs as a space-like surface in the Minkowski space.\n\nhttps://indico.math
