Ultrametric spaces;, T-orbital sets, T -dimetral sets, Fixed point, Sequentially bounded mappingsAbstract
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.
