We prove as well that if S : E --> E is dominated by a disjointly strictly singular operator, then S-2 is disjointly strictly singular.engjournal articlehttp://www.ams.org/journals/proc/2001-129-07/S0002-9939-00-05948-7/S0002-9939-00-05948-7.pdfhttp://www.ams.orgrestricted access517.98517.982.22Compact operatorsBanach latticesAnálisis funcional y teoría de operadores
