本文研究了具有多项式权的Besov和Triebel-Lizorkin型加权函数空间之间Soblev嵌入的Gelfand数和Kolmogorov数。在所谓的非极限情况下,给出了精确的渐近估计。
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 sharp asymptotic estimates are determined in the so-called non-limiting case.
