  Grey-Box Preconditioning of BE systems
Mario Bebendorf (University Leipzig)

We consider preconditioners for discrete elliptic integral operators, which are based on an H-matrix version of the LU-decomposition. Storage requirements and the amount of operations to generate and apply the preconditioner are almost linear. Numerical examples for realistic electromagnetic/electrostatic problems show that they can be efficiently applied without special adaption to the problem.
