-dimension in infinite dimensional hyperbolic cross approximation and application to parametric elliptic PDEs
Dinh Dũng, Michael Griebel, Vu Nhat Huy +1
In this article, we present a cost-benefit analysis of the approximation in tensor products of Hilbert spaces of Sobolev-analytic type. The Sobolev part is defined on a finite dime…

Approximation by translates of a single function of functions in space induced by the convolution with a given function
Dinh Dũng, Charles A. Micchelli, Vu Nhat Huy
We study approximation by arbitrary linear combinations of translates of a single function of periodic functions. We construct some methods of this approximation for functions…
