Fixed Point Theorems with Rational Expressions over a Closed Subset of Hilbert Spaces

S. A. Aniki*, E. E. Aribike, M. Raji, F. Adegboye, K. Rauf

In this paper, we prove the existence and uniqueness of a fixed point for a continuous self- mapping over a closed subset of Hilbert spaces satisfying nonlinear rational contractive-type condition. This result is extended and generalized for some positive integer powers of continuous self-mappings in Hilbert spaces.

Tripled Fixed Point Theorems in Partially Ordered G-Metric Space

S. A. Aniki*, M. Raji, F. Adegboye, E. E. Aribike, K. Rauf

Tripled fixed point theorem is an improvement to coupled fixed point. In this manuscript, we prove the existence and uniqueness of tripled fixed point for mixed monotone mapping satisfying nonlinear contractions in the framework of partially ordered G-metric space. Our results generalize and improve some results in the literature.
