BABAHMED, M.; AMRANI, A. El  and  LAZAIZ, S.. Fixed points and diametral sets for sequentially bounded mappings in orbital ultrametric spaces. Proyecciones (Antofagasta) [online]. 2020, vol.39, n.2, pp.481-493. ISSN 0716-0917.

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.

Keywords : Ultrametric spaces; T -orbital sets; T -dimetral sets; Fixed point; Sequentially bounded mappings.
