RT Journal Article T1 On a Limit Class of Approximation Spaces A1 Cobos Díaz, Fernando A1 Milman, Mario AB 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.
