Numerical solution of fractional evolution equations of Caputo type

In this project, we investigate Caputo-type fractional derivatives, time-fractional evolution equations similar to the heat equation, and their numerical solutions using a Feynman-Kac type representation. We discuss several applications of PDEs involving the Caputo derivative. We review results b...
