Harmonious coloring of multicopy of complete graphs
(Işık University Press, 2019)
In this paper, we find the harmonious chromatic number of multicopy of complete graphs Kn. We generalize the result ?H ((n + 2)Kn) > n + 1 2 ! given in [8] and also further improve the result to ?H((n + 2)Kn) ? n + 1 2 ! ...
Zagreb indices and multiplicative Zagreb indices of double graphs of subdivision graphs
(Işık University Press, 2019)
Let G be a simple graph. The subdivision graph and the double graph are the graphs obtained from a given graph G which have several properties related to the properties of G. In this paper, the first and second Zagreb and ...
Boundedly solvability of first order delay differential operators with piecewise constant arguments
(Işık University Press, 2019)
Using the methods of operator theory, we investigate all boundedly solvable extensions of a minimal operator generated by first order delay differential-operator expression with piecewise constant argument in the Hilbert ...
Measurement of planarity in product bipolar fuzzy graphs
(Işık University Press, 2019)
Bipolar fuzzy set theory provides a basis for bipolar cognitive modeling and multiagent decision analysis, where in some situations, the product operator may be preferred to the min operator, from theoretical and experimental ...
Intuitionistic fuzzy bi-implicator and properties of Lukasiewicz intuitionistic fuzzy bi-implicator
(Işık University Press, 2019)
This paper presents axiomatic as well as constructive definitions of intuitionistic fuzzy bi-implicators based on intuitionistic fuzzy t-norms and their intuitionistic fuzzy residual implicators. The inter-relationship ...
Product of bipolar intuitionistic fuzzy graphs and their degree
(Işık University Press, 2019)
In this paper, bipolar intuitionistic fuzzy graphs with four operations namely Cartesian product, composition, tensor product, normal product are defined. Also, the degrees of the vertices of the resultant graphs which are ...
Trans-Sasakian manifolds satisfying certain conditions
(Işık University Press, 2019)
The objective of the present paper is to study the properties of special weakly Ricci symmetric and generalized Ricci recurrent trans Sasakian manifolds.
Vulnerability in networks
(Işık University Press, 2019)
Recently defined exponential domination number is reported as a new measure to graph vulnerability. It is a methodology, emerged in graph theory, for vulnerability analysis of networks. Also, it gives more sensitive results ...
Tight just excellent graphs
(Işık University Press, 2019)
A graph G is ?-excellent if for every vertex v, there exists a chromatic partition ? such that {v} ? ?.A graph G is just ?-excellent if every vertex appears as a singleton in exactly one ?-partition. In this paper, a special ...
On a distribution of the process describing a service system with unreliable devices
(Işık University Press, 2019)
In the paper, the distribution is found for the process {?t, ?t}, t ? 0, in the terms of Laplace transformation. The considered process describes the queuing system with nonhomogeneous Poisson stream of demands and n ...
