General results obtained in a collaboration with A. Martínez, A. Manzano and P. Fernández-Martínez are exemplified on particular cases of operator ideals (e.g., on ideals of compact or weakly compact operators, on ideals of strictly singular or cosingular operators, etc.)engconference paperhttp://dml.cz/dmlcz/702473http://www.emis.de/restricted access517.98Interpolation between normed linear spacesOperators idealsIdeals of compact or weakly compact operatorsOn ideals of strictly singular or cosingular operatorsAnálisis funcional y teoría de operadores
