Contractor directions, directional contractors and directional contractions for solving equations

Mieczyslaw Altman

Vol. 62 (1976), No. 1, 1–18
Abstract

The concept of contractor directions appears to be a natural development of the concept of directional contractors. By using both concepts, sufficient conditions are presented for a nonlinear operator to be a mapping onto a Banach space.
