RT Journal Article T1 On reiteration and the behaviour of weak compactness under certain interpolation methods A1 Cobos Díaz, Fernando A1 Fernández-Martínez, Pedro A1 Martínez, Antón AB 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 ofthe weak compactness results.
