چکیده

This paper presents a comparative study on the distance optimality for Distance-Preserving Mappings codes generated from different constructions. Few constructions are considered to investigate the reasons behind making codes optimumwhen they reach the upper bound on the sum of the Hamming distances for certain lengths of the permutation sequences. The technique of cyclic-shift prefix or suffix of permutation symbols is used to investigate the conditions making distance-preserving mappings codes optimum.

The Existence Theorem for Contractive Mappings on $wt$-distance in $b$-metric Spaces Endowed with a Graph and its Application

In this paper, we study the existence and uniqueness of fixed points for mappings with respect to a $wt$-distance in $b$-metric spaces endowed with a graph. Our results are significant, since we replace the condition of continuity of mapping with the condition of orbitally $G$-continuity of mapping and we consider $b$-metric spaces with graph instead of $b$-metric spaces, under which can be gen...

The Banach Type Contraction for Mappings on Algebraic Cone Metric Spaces Associated with An Algebraic Distance and Endowed with a Graph

In this work, we define the notion of an algebraic distance in algebraic cone metric spaces defined by Niknam et al. [A. Niknam, S. Shamsi Gamchi and M. Janfada, Some results on TVS-cone normed spaces and algebraic cone metric spaces, Iranian J. Math. Sci. Infor. 9 (1) (2014), 71--80] and introduce some its elementary properties. Then we prove the existence and uniqueness of fixed point for a B...

Distance-preserving mappings from binary vectors to permutations

Mappings of the set of binary vectors of a fixed length to the set of permutations of the same length are useful for the construction of permutation codes. In this correspondence, several explicit constructions of such mappings preserving or increasing the Hamming distance are given. Some applications are given to illustrate the usefulness of the construction. In particular, a new lower bound o...

Designing Distance-Preserving Fault-Tolerant Topologies

DESIGNING DISTANCE-PRESERVING FAULT-TOLERANT TOPOLOGIES By Sitarama Swamy Kocherlakota The objective of designing a fault-tolerant communication network (CN) is to maintain its functionality in the presence of failures. The approaches taken in designing fault-tolerant systems can be classified, in general, by the functionality criteria. There are two functionality criteria that have received mu...
