Anisotropic, interpolatory subdivision and multigrid
Maria Charina, Marco Donatelli, Lucia Romani +1
In this paper, we present a family of multivariate grid transfer operators appropriate for anisotropic multigrid methods. Our grid transfer operators are derived from a new family…
Convergence and normal continuity analysis of non-stationary subdivision schemes near extraordinary vertices and faces
Costanza Conti, Marco Donatelli, Lucia Romani +1
Convergence and normal continuity analysis of a bivariate non-stationary (level-dependent) subdivision scheme for 2-manifold meshes with arbitrary topology is still an open issue.…
Spectral analysis and multigrid preconditioners for two-dimensional space-fractional diffusion equations
Hamid Moghaderi, Mehdi Dehghan, Marco Donatelli +1
Fractional diffusion equations (FDEs) are a mathematical tool used for describing some special diffusion phenomena arising in many different applications like porous media and comp…
