Resumen de On Banach ideals satisfying Co (A (S, Y)) = A (X, Co(Y))

Juan Manuel Delgado Sánchez, Cándido Piñeiro Gómez

• We characterize Banach ideals [A, a] satisfying the equality c0(A(X, Y )) = A(X, c0(Y )) for all Banach spaces X and Y . Among other results we have proved that K (the normed operator ideal of all compact operators with the operator norm) is the only injective Banach ideal satisfying the equality.
