Fractional reaction-diffusion with Caputo derivative

I'm interested in the following Cauchy problem for a linear diffusion equation $$ \begin{cases} {^C}\!D^{a}_tu(t,x) = \sigma\Delta u(t,x),\\ u(0)=u_0\in X. \end{cases} $$ where ${^C}\!D^{\sigma}_t$ de …

Time dependent reaction-diffusion semigroup

I'm interested in the following linear reaction-diffusion equation \begin{align*} &\partial_tu(t,x) = \sigma(t)\Delta u(t,x),\\ & u(0)=u_0\in X \end{align*} where $X$ is a Banach space and $\sigma(t)$ …
