%0 Journal Article %A Cobos, Fernando %A Fernández-Cabrera, Luz M. %A Martínez, Antón %A Pustylnik, Evgeniy %T Some Interpolation Results that are the Exclusive Property of Compact Operators %D 2002 %@ 0308-2105 %U https://hdl.handle.net/20.500.14352/57223 %X We show that certain interpolation results for compact operators established by Cobos and co-workers cannot be extended to general closed operator ideals. We shallalso characterize compactness of an embedding in terms of functions related to the classical K- and J -functionals of interpolation theory. %~
