Preasymptotics and asymptotics of approximation numbers of anisotropic Sobolev embeddings

JIa Chen, Heping Wang

In this paper, we obtain the preasymptotic and asymptotic behavior and strong equivalences of the approximation numbers of the embeddings from the anisotropic Sobolev spaces $W_2^{…

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 $…
