Even vertex odd mean labeling of transformed trees
(Işık University Press, 2020)
Let G = (V;E) be a graph with p vertices and q edges. A graph G is said have an even vertex odd mean labeling if there exists a function f: V (G) →{0; 2; 4;:::; 2q} satisfying f is 1-1 and the induced map f*: E(G) → {1; ...
Convolutions of a subclass of harmonic univalent mappings
(Işık University Press, 2020)
The main object of this paper is to investigate the convolution of a subclass of harmonic univalent mappings which is denoted by fa and generalized harmonic univalent mapping which is denoted by Pc. We obtained Pc ∗ fa is ...
Periodic and semi-periodic eigenvalues of hill's equation with symmetric double well potential
(Işık University Press, 2020)
In this paper, some estimates are derived explicitly for periodic and semiperiodic eigenvalues of Hill’ s equation with symmetric double well potentials. Also, lengths of the instability intervals are obtained and bounds ...
New concepts on m-polar interval-valued intuitionistic fuzzy graph
(Işık University Press, 2020)
Theoretical concepts of graphs are highly utilized by computer science applications. Especially in research areas of computer science such as data mining, image segmentation, clustering, image capturing and networking. The ...
Total colorings of core-satellite, cocktail party and modular product graphs
(Işık University Press, 2020)
A total coloring of a graph G is a combination of vertex and edge colorings of G. In other words, is an assignment of colors to the elements of the graph G such that no two adjacent elements (vertices and edges) receive a ...
Mathematical modelling of one dimensional temperature distribution as a function of laser intensity on carbon fiber reinforced poly(Ether-Ether-Ketone)-(PEEK) composite

Existence of a positive solution for superlinear Laplacian equation via mountain pass theorem
(Işık University Press, 2020-04-07)
In this paper, we are going to show a nonlinear laplacian equation with the Dirichlet boundary value as follow has a positive solution: ( −∆u + V (x)u = g(x, u) x ∈ Ω u = 0 x ∈ ∂Ω where, ∆u = div(∇u) is the laplacian ...
Study of subclasses of starlike and convex functions
(Işık University Press, 2020)
In this article, we introduce new subclasses of starlike and convex functions by using a new differential operator defined in the open unit disk U. We study the geometric properties of such subclasses of starlike and convex ...
A note on some new Pδ-transforms of ₂F₂ generalized hypergeometric functions
(Işık University Press, 2020-04-24)
In this note, we aim to establish Pδ-transforms of ₂F₂ generalized hypergeometric functions in terms of gamma functions. The results are established from the generalized classical summation theorems due to Gauss’s second, ...
