Self-similar solution for fractional Laplacian in cones (2307.01825v2)
Published 4 Jul 2023 in math.PR
Abstract: We construct a self-similar solution of the heat equation for the fractional Laplacian with Dirichlet boundary conditions in every fat cone. As applications, we give the Yaglom limit and entrance law for the corresponding killed isotropic stable L\'{e}vy process and precise large-time asymptotics for solutions of the Cauchy problem in the cone.
