Title: Discrete Nonlocal Isoperimetric Inequality and Analysis of the Long-Range Bi-Axial Ising Model
Date: May 30, 2025, at 14:30, 2BC30
Abstract: We consider a generalization of the classical perimeter, referred to as the nonlocal bi-axial discrete perimeter, in which not only the external boundary of a polyomino contributes to the perimeter, but all its internal and external components. In particular, this nonlocal bi-axial perimeter is a fractional function that depends on the shape of the given geometrical figure and on a parameter λ>1, which accounts for the long-range effect. We tackle the nonlocal discrete isoperimetric problem analyzing and characterizing the minimizers within the class of polyominoes with a fixed area. The solution of this isoperimetric problem provides a rigorous foundation for studying the metastable behavior of the long-range bi-axial Ising model.
Vi aspettiamo numerosi!
