On geometric multigrid methods for triangular grids using three-coarsening strategy

This paper deals with the design of efficient geometric multigrid methods on hierarchical triangular grids using a three-coarsening strategy. In [F.J. Gaspar, J.L. Gracia, F.J. Lisbona, Fourier analysis for multigrid methods on triangular grids, SIAM J. Sci. Comput., in press], a Local Fourier Analy...
