Optimal Quadrature Formulas for the Sobolev Space
Erich Novak, Shun Zhang
We study optimal quadrature formulas for arbitrary weighted integrals and integrands from the Sobolev space . We obtain general formulas for the worst case error depend…
s-Numbers of compact embeddings of function spaces on quasi-bounded domains
Shun Zhang, Alicja Gąsiorowska
We prove asymptotic formulas for the behavior of approximation, Gelfand, Kolmogorov and Weyl numbers of Sobolev embeddings between Besov and Triebel-Lizorkin spaces defined on quas…
Gelfand and Kolmogorov numbers of Sobolev embeddings of weighted function spaces II
Shun Zhang, Gensun Fang, Fanglun Huang
We consider the Gelfand and Kolmogorov numbers of compact embeddings between weighted function spaces of Besov and Triebel-Lizorkin type with polynomial weights in the non-limiting…
Gelfand and Kolmogorov numbers of Sobolev embeddings of weighted function spaces
Shun Zhang, Gensun Fang
In this paper we study the Gelfand and Kolmogorov numbers of Sobolev embeddings between weighted function spaces of Besov and Triebel-Lizorkin type with polynomial weights. The sha…
