Finite element and box-method discretizations for fractional elliptic problems with quadrature and mass lumping
Kelvin J. R. Almeida-Sousa, David Bolin, Alexandre B. Simas
We analyze numerical approximation of the fractional elliptic problem , , where is a second-order self-adjoint elliptic operator with homogeneous Dirichlet or Ne…
