Remarks on Some Recent Fixed Point Results onQuaternion-Valued Metric Spaces

Abstract EN

Very recently, Ahmed et al.

introduced the notion of quaternion-valued metric as a generalization of metric and proved a common fixed point theorem in the context of quaternion-valued metric space.

In this paper, we will show that the quaternion-valued metric spaces are subspaces of cone metric spaces.

Consequently, the fixed point results in such spaces can be derived as a consequence of the corresponding existing fixed point result in the setting cone metric spaces.
