Normal Structure and Contractions which diminish Radius in Metric and Banach Spaces
Abdelkader Dehici, Najeh Redjel, Sami Atailia
In this paper, by using admissible sets, we give some fixed point results for orbitally contractions which diminish the radius of invariant convex subsets and orbits. Furthermore,…

Fixed points of asymptotically nonexpansive mappings with center 0 and applications
Abdelkader Dehici, Sami Atailia, Najeh Redjel
In this paper, we investigate the existence of fixed points for asymptotically nonexpansive mappings with center 0 defined on closed convex subsets of various Banach spaces. Three…

The fixed point property for -mappings and unbounded sets
Sami Atailia, Abdelkader Dehici, Najeh Redjel
We prove that a closed convex subset of a real Hilbert space has the fixed point property for -mappings if and only if is bounded. Some convergence results about t…
