Optimal extensions of compactness properties for operators on Banach function spaces
Calabuig, J. M.; Jiménez-Fernández, Eduardo; Juan, M.A.; Sánchez Pérez, Enrique A. Elsevier (2015-04)Compactness type properties for operators acting in Banach function spaces are not always preserved when the operator is extended to a bigger space. Moreover, it is known that there exists a maximal (weakly) compact linear ... -
Radon-Nikodým derivatives for vector measures belonging to Köthe function spaces
Calabuig, J. M.; Gregori, Pablo; Sánchez Pérez, Enrique A. Elsevier (2008)Let m, n be a couple of vector measures with values on a Banach space. We develop a separation argument which provides a characterization of when the Radon-Nikodým derivative of n with respect to m-in the sense of the ...
