Here an(T) denote the approximation numbers. The theorem is in formal analogy to the Lp-type theorem for approximation number ideals.On some operator ideals defined by approximation numbersbook parthttp://cisne.sim.ucm.es/record=b1051616~S6*spimetadata only access517.982.22Espacios de BanachAnálisis funcional y teoría de operadores
