Mohammed Babahmed, Abdelkhalek El Amrani, Samih Lazaiz
In this paper, the T -orbital ultrametric spaces are introduced and a fixed point theorem for sequentially bounded mappings is given. Our main result extends some known theorems for nonexpansive mappings. Examples are given to support our work.
