Ways to treat a diffusion problem with the fractional Caputo derivative
[ Abstract ]
The problem
\[
u_t = (D^\alpha u)_x + f
\]
augmented with initial and boundary data appear in model of subsurface flows. Here, $D^\alpha u$ denotes the fractional Caputo derivative of order $\alpha \in (0,1)$.
We offer three approaches:
1) from the point of view of semigroups;
2) from the point of view of the theory of viscosity solutions;
3) from the point of view of numerical simulations.
This is a joint work with T. Namba, K. Ryszewska, V. Voller.
