Joint BCAM-UPV/EHU Data Science and Artificial Intelligence seminar: A variational approach to nonlocal interactions: discrete-to-continuum analysis, ground states and geometric evolutions.
Date: Thu, May 25 2023
Location: Maryam Mirzakhani Seminar Room at BCAM
Speakers: Andrea Kubin (he/him) (Technische Universität München)
We consider a core-radius approach to nonlocal perimeters governed by isotropic kernels having critical and supercritical exponents, extending the nowadays classical notion of s-fractional perimeter, defined for 0 < s < 1, to the case s>1.
In the second part of the talk we introduce a model for hard spheres interacting through attractive Riesz type potentials, and we study its thermodynamic limit.
In the third part of the talk we prove that s -fractional heat flows converge to the standard heat flow as s go to 1, and to a degenerate ODE type flow as s go to 0.
