Resumen de On reiteration and the behaviour of weak compactness under certain interpolation methods

Antonio Martínez Abejón , P. Fernández-Martínez, Fernando Cobos Díaz

• This article deals with $K$- and $J$-spaces defined by means of polygons. First we establish some reiteration formulae involving the real method, and then we study the behaviour of weakly compact operators. We also show optimality of the weak compactness results.
