Iterative process of nonlinear equations involving k-subaccretive operators.;

Iterative approximation & stability for solutions of the equations involving k-subaccretive operators;

Where T is a k-subaccretive Operator.

This paper introduces a new conception of φ-subaccretive operator and establish the strong convergence of Ishikawa iterative process to a solution of the equation x+Tx=f,where the T is a φ-subaccretive operator in an arbitrary real Banach space.

The influemce of parameter on accretive operator;

An iterative method is designed to advance the Ishikawa iteration and solve perturbed equations of accretive operators.

Some properties of accretive operators in reflexive Banach spaces were studied.

A necessary and Sufficient condition is proved for generalized steepest descent approximation to converge to the zero of m-accretive operators.

Explicit iterative methods for the approximation of zeros of accretive operators A:X→2~X is given.

By using Leray-Schauder degree,some results of the eigenvalue problem for accretive operators with compact perturbations are given.

By studying the properties of A-accretive operator,the author extends the concept of resolvent operator associated with the H -accretive operator to the new A-accretive operator.
