3. FIXED POINT RESULTS FOR MULTI-VALUED GRAPH CONTRACTIONS ON A SET ENDOWED WITH TWO METRICS.

Author

Petruşel, A. and Petruşel, G.

Subjects
*METRIC spaces
Abstract

In this paper we will study existence, uniqueness and data dependence of the fixed points of multi-valued operators on a set endowed with two metrics. The case of multi-valued graph contractions is considered. Then, an extension to a more general contraction type condition is also given. [ABSTRACT FROM AUTHOR]

6. COUPLED FIXED POINT THEOREMS FOR SYMMETRIC CONTRACTIONS IN b-METRIC SPACES WITH APPLICATIONS TO OPERATOR EQUATION SYSTEMS.

Author

PETRUŞEL, A., PETRUŞEL, G., SAMET, B., and YAO, J.-C.

Subjects
*FIXED point theory, *METRIC spaces, *OPERATOR equations
Abstract

In this paper, we will consider coupled fixed point problems in b-metric spaces for single-valued operators satisfying a symmetric contraction condition. On one hand, existence and uniqueness of the solution and, on the other hand, data dependence, well-posedness, Ulam-Hyers stability, limit shadowing property of the coupled fixed point problem are discussed. The approach is based on the application of a Ran-Reurings type fixed point theorem for an appropriate operator on the Cartesian product space. Some applications to a system of integral equations and to a periodic boundary value problems are also given. [ABSTRACT FROM AUTHOR]
