Eccentricity based topological indices of some graphs
(Işık University Press, 2020)Topological indices are real numbers that are presented as graph parameters introduced during studies conducted on the molecular graphs in chemistry and can describe some physical and chemical properties of molecules. In ... -
Some parameters of the identity graph of multigroup
(Işık University Press, 2020)B. Sharada et. al. [17], have introduced the concept of the identity graph of a multigroup ?(G, E), which derived a representation of the multigroup as a graph. In this paper, we study some parameters of ?(G, E). -
A geometrical study of wang-chen system in view of KCC theory
(Işık University Press, 2020)The present paper discuss the stability of Wang-Chen system from the approach of KCC theory. we show that the system is Jacobi unstable for any value of parameter where as it is linear stable for some choosen parameter. ... -
Some quadratic transformations motivated by the work of kummer and their generalizations
(Işık University Press, 2020)In this paper, we construct two quadratic transformations influenced by the work of Kummer and application of hypergeometric summation theorems of argument “two”. Further, we establish some generalizations of these quadratic ... -
On a new class of integrals involving generalized hypergeometric function ?F?

Generalized lorentz group of space-time transformations
(Işık University Press, 2020)We examine how Lorentz Symmetry (LS) breaks down in Yarman-Arik-Kholmetskii (YARK) theory of gravitation through an entirely different mechanism than that under metric theories of gravity. Said mechanism can be right away ... -
Solving of a neumann boundary value problem through variational methods

Skew-normal revisited via some ranked set sampling schemes
(Işık University Press, 2020-04-24)Ranked set sampling (RSS) was first introduced by McIntyre (1952) as a competitor of simple random sampling (SRS), the most common tool in the statistical methods. When the sample size is not large enough, it may be difficult ... -

Zero forcing and power domination for lexicographic product of two fuzzy soft graphs
(Işık University Press, 2020)Zero forcing and power domination are iterative processes on graphs where an initial set of vertices are observed, and additional vertices become observed based on some rules. In both cases, the goal is to eventually observe ... -
