Our result refers to general Banach N-tuples. We also derive estimates for entropy numbers if some of the N-tuples reduce to a single Banach space.engjournal articlehttps//doi.org/10.1017/S0017089599970404http://journals.cambridge.org/download.php?file=%2FGMJ%2FGMJ41_01%2FS0017089599970404a.pdf&code=4690f1c1restricted access517.98Measure of Non-CompactnessInterpolated Operator Acting from A J-Space into A K-SpaceEntropy NumbersAnálisis funcional y teoría de operadores
