Guaranteed lower bounds for cost functionals of time-periodic parabolic optimization problems
Monika Wolfmayr
In this paper, a new technique is shown for deriving computable, guaranteed lower bounds of functional type (minorants) for two different cost functionals subject to a parabolic ti…
A fast Fourier transform based direct solver for the Helmholtz problem
Jari Toivanen, Monika Wolfmayr
This paper is devoted to the efficient numerical solution of the Helmholtz equation in a two- or three-dimensional rectangular domain with an absorbing boundary condition (ABC). Th…
On the a posteriori error analysis for linear Fokker-Planck models in convection-dominated diffusion problems
Svetlana Matculevich, Monika Wolfmayr
This work is aimed at the derivation of reliable and efficient a posteriori error estimates for convection-dominated diffusion problems motivated by a linear Fokker-Planck problem…
Functional a posteriori error estimates for parabolic time-periodic boundary value problems
Ulrich Langer, Sergey Repin, Monika Wolfmayr
The paper is concerned with parabolic time-periodic boundary value problems which are of theoretical interest and arise in different practical applications. The multiharmonic finit…
