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…

Multigrid methods: grid transfer operators and subdivision schemes
Maria Charina, Marco Donatelli, Lucia Romani +1
The convergence rate of a multigrid method depends on the properties of the smoother and the so-called grid transfer operator. In this paper we define and analyze new grid transfer…
