Efficient computation of highly oscillatory integrals by using QTT tensor approximation
Boris Khoromskij, Alexander Veit
We propose a new method for the efficient approximation of a class of highly oscillatory weighted integrals where the oscillatory function depends on the frequency parameter $ω\geq…

Adaptive Time Discretization for Retarded Potentials
Stefan Sauter, Alexander Veit
In this paper, we will present advanced discretization methods for solving retarded potential integral equations. We employ a -partition of unity method in time and a c…
