A1. By means of a direct approach, we show that the interpolation spaces on (A0;A1) generated by the function parameter tµ(1 + j log tj)¡b can be expressed in terms of classical real inter-polation spaces. Applications are given to Zygmund spaces Lp(log L)b(­), Lorentz-Zygmund function spaces and operator spaces de¯ned by using approximation num- bers.engjournal articlehttps//doi.org/10.4171/ZAA/1311http://www.ems-ph.org/journals/show_abstract.php?issn=0232-restricted access517.98Operator IdealsSobolev SpacesOrlicz SpacesParameterEntropyLogarithmic Interpolation SpacesReal Interpolation with a Parameter FunctionZygmund Function SpacesLorentz-Zygmund function spacesMathematicsMultidisciplinary SciencesAnálisis funcional y teoría de operadores
