Nonlocal diffusion problems that approximate a parabolic equation with spatial dependence

In this paper, we show that smooth solutions to the Dirichlet problem for the parabolic equation (Formula presented.), with v(x, t) = g(x, t), (Formula presented.) can be approximated uniformly by solutions of nonlocal problems of the form (Formula presented.), with (Formula presented.) , (Formula p...
