RT Journal Article T1 Limiting real interpolation methods for arbitrary Banach couples A1 Cobos Díaz, Fernando A1 Segurado, Alba AB We study limiting K- and J-methods for arbitrary Banach couples. They are related by duality and they extend the methods already known in the ordered case. We investigate the behaviour of compact operators and we also discuss the representation of the methods by means of the corresponding dual functional. Finally, some examples of limiting function spaces are given.
