A fast directional algorithm for high-frequency electromagnetic scattering
This paper is concerned with the fast solution of high frequency electromagnetic scattering problems using the boundary integral formulation. We extend the O(N log N) directional ...

Linear Systems for Regular Hedge Languages
We propose linear systems of hedge language equations (LSH) as a formalism to represent regular hedge languages. These linear systems are suitable for several computations in the a...

Numerical Invariantization for Morphological PDE Schemes
Abstract. Based on a new, general formulation of the geometric method of moving frames, invariantization of numerical schemes has been established during the last years as a powerf...
