A note about EC- $(s, t)$ -weak tractability of multivariate approximation with analytic Korobov kernels

Heping Wang

This note is devoted to discussing multivariate approximation of continuous functions on $[0, 1]^{d}$ with analytic Korobov kernels in the worst and average case settings. We only con…

Average Case $(s, t)$ -weak tractability of non-homogenous tensor product problems

Jia Chen, Heping Wang, Jie Zhang

We study $d$ -variate problem in the average case setting with respect to a zero-mean Gaussian measure. The covariance kernel of this Gaussian measure is a product of univariate ker…

Average Case tractability of multivariate approximation with Gaussian kernels

Jia Chen, Heping Wang

We study the problem of approximating functions of $d$ variables in the average case setting for the $L_{2}$ space $L_{2, d}$ with the standard Gaussian weight equipped with a zero-me…
