Hernández, Francisco L. ; Sánchez de los Reyes, Víctor Manuel ; Semenov, Evgeny M. | Elsevier | 2004-03-15Strict singularity and strict co-singularity of inclusions between symmetric sequence spaces are studied. Suitable conditions are provided involving the associated fundamental functions. The special case of Lorentz and Marcinkiewicz spaces is ch[...]![]()

An operator A mapping a Banach space E into a Banach space F is called strictly singular (or Kato) if any restriction of A to an infinite-dimensional subspace of E is not an isomorphism. The paper deals with the problem of describing all co[...]![]()

Sánchez de los Reyes, Víctor Manuel ; Semenov, Evgeny M. ; Hernández, Francisco L. | Interperiodica | 2005The paper deals with the strict singularity and the disjoint strict singularity of the canonical embedding between couples of rearrangement invariant spaces E and F. Let E c F. This embedding is called strictly singular (disjointly strictly sing[...]![]()

Hernández, Francisco L. ; Sánchez de los Reyes, Víctor Manuel ; Semenov, Evgeny M. | Springer | 2008-01It is given a complete characterization of the strict singularity and the disjoint strict singularity of the inclusions E ? L1 + L? for the class of rearrangement invariant function spaces E on the [0,?) interval. Their relationship is also anal[...]![]()

Let E and F be Banach spaces. 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[...]![]()

Hernández, Francisco L. ; Semenov, Evgeny M. ; Tradacete Pérez, Pedro | American Mathematical Society | 2010-02We study the class Vp of strictly singular non-compact operators on Lp spaces. This allows us to obtain interpolation results for strictly singular operators on Lp spaces. Given 1 ? p
