Closed operator ideals and limiting real interpolation

Luz M. Fernández-Cabrera, Antón Martínez (2014)

Studia Mathematica

Similarity:

We establish interpolation properties under limiting real methods for a class of closed ideals including weakly compact operators, Banach-Saks operators, Rosenthal operators and Asplund operators. We show that they behave much better than compact operators.

Interpolation theory and measures related to operator ideals

Cobos, Fernando

Similarity:

Given any operator ideal , there are two natural functionals γ ( T ) , β ( T ) that one can use to show the deviation of the operator T to the closed surjective hull of and to the closed injective hull of , respectively. We describe the behaviour under interpolation of γ and β . The results are part of joint works with A. Martínez, A. Manzano and P. Fernández-Martínez.
