Multi-Level Minimal Residual Smoothing: A Family of General Purpose Multigrid Acceleration Techniques

, 2007
We employ multi-level minimal residual smoothing (MRS) as a pre-optimization technique to accelerate standard multigrid convergence. The MRS method is used to improve the current multigrid iterate by smoothing its corresponding residual before the latter

Nodal-Layer Resolution and Morse-Index Reliability in Numerical Continuation of Saturating Semilinear Elliptic Problems

A numerically converged nonlinear solution need not have a numerically converged Morse index. We study this separation for sign-changing solutions of saturating semilinear elliptic equations \((-\Delta u=\sigma g(u))\) with homogeneous Dirichlet ...
