Computational Complexity of Hierarchically Adapted Meshes

We show that for meshes hierarchically adapted towards singularities there exists an order of variable elimination for direct solvers that will result in time complexity not worse than [Formula: see text], where N is the number of nodes and q is the dimensionality of the singularity. In particular,...
