Luogo: Aule Enriques ore 14:00
Statistical mechanical models (dimer, Ising, resistor) model physical phenomena such as crystal formation, ferromagnetism, and electrical conductance. In recent years, it has been discovered that such models on planar graphs are closely connected to the geometry and combinatorics of the Grassmannian, specifically to the positive Grassmannian.
