Abstract
In this paper, Φ-pseudo-contractive operators and Φ-accretive operators, more general than the strongly pseudo-contractive operators and strongly accretive operators, are introduced. By setting up a new inequality, authors proved that if is a uniformly continuous Φ-pseudo-contractive operator then T has unique fixed point q and the Mann iterative sequence with random errors approximates to q. As an application, the iterative solution of nonlinear equation with Φ-accretive operator is obtained. The results presented in this paper improve and generalize some corresponding results in recent literature.
Highlights
Introduction and PreliminariesIn 1994, Chidume [1] solved a problem dealt with the fixed point for the class of Lipschitz strictly pseudo-contractive operators in uniformly smooth Banach space X
He proved that the Ishikawa iterative sequence converges strongly to the unique fixed point of T in K where K ⊂ X and T : K → K is Lipschitz strictly pseudo-contractive
The objective of this paper is to introduce Φ-pseudo-contractive operators—a class of operators which are more general than the φ -strongly pseudo-contractive operators and to study the problems of existence, uniqueness and the iterative approximate method of fixed point by setting up a new inequality in arbitrary Banach space
