Prime labeling in the context of subdivision of some cycle related graphs
(Işık University Press, 2021)
A prime labeling on a graph G of order n is a bijection from the set of vertices of G into the set of first n positive integers such that any two adjacent vertices in G have relatively prime labels. The results about prime ...
Fixed point theorems for generalized (?, ?)-weak contractions
(Işık University Press, 2017)
In this paper, we prove some fixed point theorems for generalized (?, ?)-weak contractive mappings in a metric space. Our result generalized and extend recent results of Singh et al.[16, Theorem 2.1], Dori´c [7, Theorem ...
Coefficient estimate of the second Hankel determinant of logarithmic coefficients for the subclass of close-to-convex function
(Işık University Press, 2024-04)
Let S denote the subclass of the analytic function and univalent functions in D, where D is defined as a unit disk, and having the Taylor representation form of S. In this paper, we will be obtaining the second Hankel ...
Numerical solution of the interrelated differential equation of motion in phonon engineering
(Işık University Press, 2017)
In this work, we study numeric calculations of phonon modes in nanostructures. The motion equation of atoms in a crystal with some simplification, results in a second order ordinary differential equation and two interrelated ...
On the partial sums of convex harmonic univalent functions
(Işık University Press, 2019)
Partial sums of analytic univalent functions and partial sums of starlike have been investigated extensively by several researchers. In this paper, we investigate a partial sums of convex harmonic functions that are univalent ...
A Galerkin-like scheme to determine curves of constant breadth in Euclidean 3-space
(Işık University Press, 2021)
The main focus of this study is to obtain the approximate solutions of a first order linear differential equation system characterizing curves of constant breadth in Euclidean 3-space. For this purpose, we outline a ...
A numerical solution of an inverse parabolic problem
(Işık University Press, 2012-05-07)
In this paper, we will first study the existence and uniqueness of the solution of an inverse problem for a linear equation with non-linear boundary conditions (radiation terms), via an auxiliary problem. Furthermore, a ...
Necessary and sufficient conditions for the wave packet frames on positive half-line
(Işık University Press, 2016-04-22)
In this paper, we consider wave packet systems as special cases of generalized shift-invariant systems, a concept studied by Hern´andez, Lebate and Weiss. The objective of the paper is to construct wave packet frames on ...
Partition energy of some trees and their generalized complements
(Işık University Press, 2020)
Let G = (V, E) be a graph and Pk = {V1, V2, . . . , Vk} be a partition of V . The k-partition energy of a graph G with respect to partition Pk is denoted by EPk (G) and is defined as the sum of the absolute values of ...
Existence of nonoscillatory solutions for second-order 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 ...
