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^…

Sparse polynomial approximation of parametric elliptic PDEs. Part I: affine coefficients

Markus Bachmayr, Albert Cohen, Giovanni Migliorati

We consider elliptic partial differential equations with diffusion coefficients that depend affinely on countably many parameters. We study the summability properties of polynomial…
