Compressive sensing Petrov-Galerkin approximation of high-dimensional parametric operator equations

Holger Rauhut, Christoph Schwab

We analyze the convergence of compressive sensing based sampling techniques for the efficient evaluation of functionals of solutions for a class of high-dimensional, affine-paramet…

Higher Order Quasi Monte-Carlo Integration in Uncertainty Quantification

Josef Dick, Quoc Thong Le Gia, Christoph Schwab

We review recent results on dimension-robust higher order convergence rates of Quasi-Monte Carlo Petrov-Galerkin approximations for response functionals of infinite-dimensional, pa…

Efficient Resolution of Anisotropic Structures

Wolfgang Dahmen, Chunyan Huang, Gitta Kutyniok +3

We highlight some recent new delevelopments concerning the sparse representation of possibly high-dimensional functions exhibiting strong anisotropic features and low regularity in…

Higher order Quasi-Monte Carlo integration for holomorphic, parametric operator equations

Josef Dick, Quoc T. Le Gia, Christoph Schwab

We analyze the convergence of higher order Quasi-Monte Carlo (QMC) quadratures of solution-functionals to countably-parametric, nonlinear operator equations with distributed uncert…

Multi-level higher order QMC Galerkin discretization for affine parametric operator equations

Josef Dick, Frances Kuo, Quoc Thong Le Gia +1

We develop a convergence analysis of a multi-level algorithm combining higher order quasi-Monte Carlo (QMC) quadratures with general Petrov-Galerkin discretizations of countably af…
