Strong equivalences of approximation numbers and tractability of weighted anisotropic Sobolev embeddings

JiDong Hao, Heping Wang

In this paper, we study multivariate approximation defined over weighted anisotropic Sobolev spaces which depend on two sequences $a = {a_{j}}_{j \geq 1}$ and ${\bf b}=\{b_j\}_{j…

Average case tractability of additive random fields with Korobov kernels

Jia Chen, Heping Wang

We investigate average case tractability of approximation of additive random fields with marginal random processes corresponding to the Korobov kernels for the non-homogeneous case…

Probabilistic and average linear widths of weighted Sobolev spaces on the ball equipped with a Gaussian measure

Heping Wang

Let $L_{q, μ}$ , $1 \leq q \leq \infty$ , denotes the weighted $L_{q}$ space of functions on the unit ball $B^{d}$ with respect to weight $(1 - ∥ x ∥_{2}^{2})^{μ - \frac{1}{2}}, μ \geq 0$ , and let $…
