Robust Preconditioners Based on the Finite Element Framework

Robust Preconditioners Based on the Finite Element Framework

Robust preconditioners on block-triangular and block-factorized form for three types of linear systems of two-by-two block form are studied in this thesis. The first type of linear systems, which are dense, arise from a boundary element type of discretization of crack propagation problems. Numerical...
