Abstract
The main goal of this work is to prove that every non-negative strong solution u(x, t) to the problem (Formula presented.) can be written as (Formula presented.) where (Formula presented.) and (Formula presented.) This result shows uniqueness in the setting of non-negative solutions and extends some classical results for the heat equation by Widder in [15] to the nonlocal diffusion framework.
