Numerical approximations for fractional elliptic equations via the method of semigroups

Nicole Cusimano, Félix del Teso, Luca Gerardo-Giorda

We provide a novel approach to the numerical solution of the family of nonlocal elliptic equations $(-\Delta {)}^{s}u=f$ in $\Omega$, subject to some homogeneous boundary conditions $\mathcal{B}(…
