A Riesz basis Galerkin method for the tempered fractional Laplacian

Zhijiang Zhang, Weihua Deng, George Em Karniadakis

The fractional Laplacian ${\Delta }^{\beta /2}$ is the generator of $\beta$-stable Lévy process, which is the scaling limit of the Lévy fight. Due to the divergence of the second moment of the jump…
