Diffusion Coefficients Estimation for Elliptic Partial Differential Equations

Andrea Bonito, Albert Cohen, Ronald DeVore +2

This paper considers the Dirichlet problem $- div (a \nabla u_{a}) = f on D, u_{a} = 0 on \partial D,$ for a Lipschitz domain $D\subset \m…

Approximation of high-dimensional parametric PDEs

Albert Cohen, Ronald Devore

Parametrized families of PDEs arise in various contexts such as inverse problems, control and optimization, risk assessment, and uncertainty quantification. In most of these applic…

Kolmogorov widths under holomorphic mappings

Albert Cohen, Ronald Devore

If $L$ is a bounded linear operator mapping the Banach space $X$ into the Banach space $Y$ and $K$ is a compact set in $X$ , then the Kolmogorov widths of the image $L (K)$ do not ex…
