Billiards in magnetic fields: A molecular dynamics approach
M. Aichinger, S. Janecek, E. Rasanen
We present a computational scheme based on classical molecular dynamics to study chaotic billiards in static external magnetic fields. The method allows to treat arbitrary geometri…
Optimal Time Decay of the Vlasov-Poisson-Boltzmann System in
Renjun Duan, Robert M. Strain
The Vlasov-Poisson-Boltzmann System governs the time evolution of the distribution function for the dilute charged particles in the presence of a self-consistent electric potential…
Hierarchical models in statistical inverse problems and the Mumford--Shah functional
Tapio Helin, Matti Lassas
The Bayesian methods for linear inverse problems is studied using hierarchical Gaussian models. The problems are considered with different discretizations, and we analyze the pheno…
Causality Analysis of Frequency Dependent Wave Attenuation
Kowar Richard, Scherzer Otmar, Bonnefond Xavier
The work is inspired by thermo-and photoacoustic imaging, where recent efforts are devoted to take into account attenuation and varying wave speed parameters. In this paper we deri…
A new approach to source conditions in regularization with general residual term
Jens Geissler, Bernd Hofmann
This paper addresses Tikhonov like regularization methods with convex penalty functionals for solving nonlinear ill-posed operator equations formulated in Banach or, more general,…
A Convergent Overlapping Domain Decomposition Method for Total Variation Minimization
Massimo Fornasier, Andreas Langer, Carola-Bibiane Schönlieb
This paper is concerned with the analysis of convergent sequential and parallel overlapping domain decomposition methods for the minimization of functionals formed by a discrepancy…
