This study focuses on the decay/growth rates in all L-p norms of solutions to an inhomogeneous nonlocal heat equation in a large dimension space, N > 4 beta. The rates are strongly influenced by the space-time scale and the time behavior of the spatial L-1 norm of the forcing term.
We study the decay/growth rates in all L-p norms of solutions to an inhomogeneous nonlocal heat equation in R-N involving a Caputo alpha-time derivative and a power beta of the Laplacian when the dimension is large, N > 4 beta. Rates depend strongly on the space-time scale and on the time behavior of the spatial L-1 norm of the forcing term.
