Special Solutions to the Space Fractional Diffusion Problem
arXiv:2111.01197
Abstract
We derive a fundamental solution to a space-fractional diffusion problem on the half-line. The equation involves the Caputo derivative. We establish properties of as well as formulas for solutions to the Dirichlet and Neumann problems in terms of convolution of with data. We also study integrability of derivative of solutions given in this way. We present conditions sufficient for uniqueness. Finally, we show the infinite speed of signal propagation.
