- Title
Mutually Best Approximation in D-metric Spaces.
- Authors
Malekpoor, Sh.; Shabani, Sh.; Vaezpour, S. M.
- Abstract
In this paper, we introduce the concept of mutually best approximation of x, y in D-metric space X with respect to G ⊆ X. Then we consider a special D-metric on a normed space X and introduce the topology generated by this D-metric on X, then generalize some results of best approximation for mutually best approximation.
