Entropy solutions to the fully nonlocal diffusion equations
We consider the fully nonlocal diffusion equations with nonnegative -data. Based on the approximation and energy methods, we prove the existence and uniqueness of nonnegative entropy solutions for such problems. In particular, our results are valid for the time-space fractional Laplacian equations.
