On star chromatic number of prism graph families
(Işık University Press, 2019)In this paper, we find the star chromatic number χs for the central graph of prism graph C(Yn), line graph of prism graph L(Yn), middle graph of prism graph M(Yn) and the total graph of prism graph T(Yn) for all n ≥ 3. 
Global color class domination partition of a graph
(Işık University Press, 2019)Color class domination partition was suggested by E. Sampathkumar and it was studied in [1]. A proper color partition of a finite, simple graph G is called a color class domination partition (or cdpartition) if every color ... 
SK indices, forgotten topological indices and Hyper Zagreb index of Q operator of carbon nanocone
(Işık University Press, 2019)Carbon nanocones are conical structures made from carbon and they have one dimension of order one micrometer. The physical features of these structures can be easily understood by exploiting topological indices. In this ... 
On the average lower 2domination number of a graph
(Işık University Press, 2019)Computer scientists and network scientists want a speedy, reliable, and nonstop communication. In a communication network, the vulnerability measures the resistance of the network to disruption of operation after the failure ... 
Existence of nonoscillatory solutions of secondorder neutral differential equations
(Işık University Press, 2019)We obtain some sufficient conditions for the existence of nonoscillatory solutions of nonlinear second order neutral differential equation with forcing term. Our results improve and extend some existing results. Examples ... 
Some inequalities for B⁻¹ convex functions via fractional integral operator

(Işık University Press, 2019)We investigate the nonexistence of positive solutions for a system of nonlinear RiemannLiouville fractional differential equations with pLaplacian twopoint boundary value problem. 
Existence of nonoscillatory solutions for secondorder nonlinear neutral differential equations with variable delays
(Işık University Press, 2019)In this work, an attempt is made to discuss the existence of nonoscillatory solutions of second order nonlinear neutral differential equations with variable delays. The main tools are Lebesgue’s dominated convergence theorem ... 
Distance spectra of some graph operations and some new distance equienergetic graphs of diameter 3
(Işık University Press, 2019)Two graphs of same order are said to be distance equienergetic if their distance energies are same. In this paper, we first give a partial insight on the distance spectrum of Mycielskian graphs and then we focus on ... 
On the spectra of cycles and paths
(Işık University Press, 2019)Energy of a graph was defined by E. Hückel as the sum of absolute values of the eigenvalues of the adjacency matrix during the search for a method to obtain approximate solutions of Schr¨odinger equation which include the ... 
Solution of constant coeffients partial derivative equations with Elzaki Transform method
(Işık University Press, 2019)In this study, we apply Elzaki Transform method, which is the modified version of Laplace and Sumudu transforms, for general n.th order constant coefficients partial diferential equations. With this method we can solve all ... 
Symmetric biTderivation of lattices
(Işık University Press, 2019)In this paper, the notion of a new kind of derivation is introduced for a lattice (L, ∨, ∧), called symmetric biTderivations on L as a generalization of derivation of lattices and characterized some of its related ... 
Existence of three solutions for impulsive fractional differential systems through variational methods
