Bărbătei, O.; Cofan, N.; Hedrea, C.; Stan, I. \(s\)-numbers and interpolation. (English) Zbl 1212.46106 An. Ştiinţ. Univ. Al. I. Cuza Iaşi, Ser. Nouă, Mat. 54, No. 2, 319-328 (2008). Summary: We establish some estimates for Gelfand and Kolmogorov numbers of the interpolation operator in the multidimensional case. We also analyse the interpolation property of operator ideals defined by Gelfand and Kolmogorov numbers.
