We show how the geometrical properties of uniform convexity and uniformly non-e: are inherited by real interpolation spaces for infinite families. ## Preliminaries Let D denote the unit disc {z E (c: IzI < I} and r its boundary. Let -A = { A d y ) : y E r , d , % } 17\*
## Abstract We present reiteration formulae with limiting values __ΞΈ__ = 0 and __ΞΈ__ = 1 for a real interpolation method involving slowly varying functions. Applications to the LorentzβKaramata spaces, the Fourier transform and the Riesz potential are given. In particular, our results yield improve
## Abstract We study limit __K__βspaces for general Banach couples, not necessarily ordered. They correspond to the extreme choice ΞΈ = 0, 1 in the realization of the real method as a __K__βspace. We also show the connection of these limit spaces with interpolation methods defined by the unit square
