A linear operator from E to F is said to be strictly singular if, for any subspace Q aS, E, the restriction of A to Q is not an isomorphism. A compactness criterion for any strictly singular operator from L (p) to L (q) is found. There exists a strictly singular but not superstrictly singular operator on L (p) , provided that p not equal 2.engjournal articlehttp://link.springer.com/article/10.1134/S1064562416040281http://link.springer.com/restricted access517Banach-latticesCompactAnálisis matemático1202 Análisis y Análisis Funcional
