Bărbătei, O.; Cofan, Nicolae; Stan, Ilie; Hedrea, Ciprian Entropy numbers of interpolation operators. (English) Zbl 1199.46164 An. Univ. Vest Timiș., Ser. Mat.-Inform. 46, No. 2, 3-12 (2008). Summary: We establish an estimate for entropy numbers of the interpolation operator in the multidimensional case. We also analyze the interpolation property of the entropy ideal.
