Comparison results and steady states for the Fujita equation with fractional Laplacian
Matthias Birkner, Jose Alfredo Lopez Mimbela, Anton Wakolbinger
We study a semilinear PDE generalizing the Fujita equation whose evolution operator is the sum of a fractional power of the Laplacian and a convex non-linearity. Using the Feynman-…
