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

open access: yes, 2016
We consider elliptic partial differential equations with diffusion coefficients that depend affinely on countably many parameters. We study the summability properties of polynomial expansions of the function mapping parameter values to solutions of the ...

An optimal polynomial approximation of Brownian motion [PDF]

open access: yes, 2020
In this paper, we will present a strong (or pathwise) approximation of standard Brownian motion by a class of orthogonal polynomials. The coefficients that are obtained from the expansion of Brownian motion in this polynomial basis are independent ...
