On ∇**-distance and fixed point theorems in generalized partially ordered D*-metric spaces

In this paper, we introduce a new concept on a complete generalized D*-metric space by using the concept of generalized D*-metric space (D*-cone metric space) called ∇**-distance and, by using the concept of the ∇**-distance we prove some new fixed point theorems in complete partially ordered generalized D*-metric space which is the main result of our paper.
