Algebraic multilevel preconditioners for the graph Laplacian based on matching in graphs
James Brannick, Yao Chen, Johannes Kraus +1
This paper presents estimates of the convergence rate and complexity of an algebraic multilevel preconditioner based on piecewise constant coarse vector spaces applied to the graph…
