Spectral properties of a class of Sierpinski-type Moran measures on $R^{n}$

Jia Long Chen, Xiao-Yu Yan

Let the infinite convolutions \begin{equation*} μ_{\{R_{k}\},\{D_{k}\}}=δ_{R_{1}^{-1}D_{1}}*δ_{R_{1}^{-1}R_{2}^{-1}D_{2}}*δ_{R_{1}^{-1}R_{2}^{-1}R_{3}^{-1}D_{3}}*\dotsi \end{equati…

Approximation numbers of Sobolev and Gevrey type embeddings on the sphere and on the ball -- Preasymptotics, asymptotics, and tractability

Jia Chen, Heping Wang

In this paper, we investigate optimal linear approximations ( $n$ -approximation numbers ) of the embeddings from the Sobolev spaces $H^{r} (r > 0)$ for various equivalent norms and the…
