RT Journal Article T1 Strictly singular embeddings A1 Novikov, S.Ya. A1 Semenov, Evgeny M. A1 Hernández, Francisco L. AB 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 couples of rearrangement-invariant spaces E↪F for which the embedding operator is strictly singular.
