Tensor FEM for spectral fractional diffusion
Lehel Banjai, Jens M. Melenk, Ricardo H. Nochetto +3
We design and analyze several Finite Element Methods (FEMs) applied to the Caffarelli-Silvestre extension that localizes the fractional powers of symmetric, coercive, linear ellipt…
Fully discrete approximation of parametric and stochastic elliptic PDEs
Markus Bachmayr, Albert Cohen, Dinh Dũng +1
It has recently been demonstrated that locality of spatial supports in the parametrization of coefficients in elliptic PDEs can lead to improved convergence rates of sparse polynom…
Multi-level Compressed Sensing Petrov-Galerkin discretization of high-dimensional parametric PDEs
Jean-Luc Bouchot, Holger Rauhut, Christoph Schwab
We analyze a novel multi-level version of a recently introduced compressed sensing (CS) Petrov-Galerkin (PG) method from [H. Rauhut and Ch. Schwab: Compressive Sensing Petrov-Galer…
