%0 Journal Article %A Cobos Díaz, Fernando %A Milman, Mario %T On a Limit Class of Approximation Spaces %D 1990 %@ 0163-0563 %U https://hdl.handle.net/20.500.14352/57340 %X We describe the behaviour under interpolation of a limit class of approximation spaces. We characterize them as extrapolation spaces. Moreover, we study the boundedness of certain operators on these spaces. As an application, we derive several results on Macaev operator ideals. %~
