Sparse polynomial approximation of parametric elliptic PDEs. Part II: lognormal coefficients
Markus Bachmayr, Albert Cohen, Ronald DeVore +1
Elliptic partial differential equations with diffusion coefficients of lognormal form, that is , where is a Gaussian random field, are considered. We study the $\ell^…

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…
