    Let (X; d;⪯) be a partially ordered ultrametric space and F:X X and T: X → CB(X) be a single valued and set valued mappings respectively. We give sufficient conditions for the existence of a fixed point for the contractive mappings F and 1 in the partially ordered ultrametric space X. We also investigate the existence of a fixed point for the nonexpansive mapping under those conditions.
