Matrix-Based Multigrid for Locally Refined Meshesebraic assumptions such as diagonal dominance of the coefficient matrices, we derive an aposteriori upper bound for the condition number of the V(0,0)-cycle. This result applies also to diffusion problems with variable and even discontinuous coefficients, even when the discontinuity lines don’t alig

The Multigrid Iteration elliptic PDEs. We highlight an interesting connection between multigrid and domain decomposition, and explain the various kinds of multigrid versions (including black-box multigrid and algebraic multigrid) in terms of domain decomposition.

The Indefinite Helmholtz EquationAutoMUG, the transfer operators in the BBMG version are also designed to agree with the nearly singular eigenfunction of the original PDE. We also show how to compute the spectrum of the iteration matrix in some model cases. This analysis helps in the design of the multigrid method.
