On the stability of DPG formulations of transport equations
D. Broersen, W. Dahmen, R. P. Stevenson
In this paper we formulate and analyze a Discontinuous Petrov Galerkin formulation of linear transport equations with variable convection fields. We show that a corresponding {\em…
Orthogonal Matching Pursuit under the Restricted Isometry Property
Albert Cohen, Wolfgang Dahmen, Ronald DeVore
This paper is concerned with the performance of Orthogonal Matching Pursuit (OMP) algorithms applied to a dictionary in a Hilbert space . Given an elemen…
Data Assimilation in Reduced Modeling
Peter Binev, Albert Cohen, Wolfgang Dahmen +3
We consider the problem of optimal recovery of an element of a Hilbert space from measurements obtained through known linear functionals on . Pro…
How to best sample a solution manifold?
Wolfgang Dahmen
Model reduction attempts to guarantee a desired "model quality", e.g. given in terms of accuracy requirements, with as small a model size as possible. This article highlights some…
