Reduced Sum Implementation of the BURA Method for Spectral Fractional Diffusion Problems

Stanislav Harizanov, Nikola Kosturski, Ivan Lirkov +2

The numerical solution of spectral fractional diffusion problems in the form ${\mathcal{A}}^{\alpha }u=f$ is studied, where $\mathcal{A}$ is a selfadjoint elliptic operator in a bounded do…
