Kolmogorov n-Widths of Function Classes Induced by a Non-Degenerate Differential Operator: A Convex Duality Approach

Patrick L. Combettes, Dinh Dũng

Let $P (D)$ be the differential operator induced by a polynomial $P$ , and let $U_{2}^{[P]}$ be the class of multivariate periodic functions $f$ such that $∥ P (D) (f) ∥_{2} \leq 1$ . The…

Whitney's theorem for local anisotropic polynomial L_p-approximation, 0<p<1

Dinh Dũng, Nguyen Van Dũng, Nguyen Dinh Hoa

Dinh Dũng and T. Ullrich have proven a multivariate Whitney's theorem for the local anisotropic polynomial approximation in $L_{p} (Q)$ for $1 \leq p \leq \infty$ , where $Q$ is a $d$ -pa…
