G-(F; ? )-contractions in partial rectangular metric spaces endowed wıth a graph and fixed point theorems
(Işık University Press, 2016-06-22)In this paper, the notion of G-(F, ? )-contractions in the context of partial rectangular metric spaces endowed with a graph is introduced. Some fixed point theorems for G-(F, ? )-contractions are also proved. The results ... -
About an algorithm of function approximation by the linear splines
(Işık University Press, 2016-05-05)The actual application for the problem of best approximation of grid function by linear splines was formulated. A mathematical model and a method for its solution were developed. Complexity of the problem was that it was ... -
On certain topological indices of the derived graphs of subdivision graphs
(Işık University Press, 2016-03-11)The derived graph [G]† of a graph G is the graph having the same vertex set as G, with two vertices of [G]† being adjacent if and only if their distance in G is two. Topological indices are valuable in the study of QSAR/QSPR. ... -
Some results on the distance r-b-coloring in graphs
(Işık University Press, 2016)Given a positive integer r, two vertices u, v ? V (G) are r- independent if d(u, v) > r. A partition of V (G) into r-independent sets is called a distance r-coloring. A study of distance r-coloring and distance r-b-coloring ... -
Stability of a functional equation in complex banach spaces
(Işık University Press, 2016-03-14)Using fixed point technique, in the present paper , we wish to examine generalization of the Hyers-Ulam-Rassias stability theorem for the functional equations f ( 2 x + i y ) + f ( x + 2 i y ) = 4 f ( x + i y ) + f ( x ) ... -
On a sum form functional equation
(Işık University Press, 2016-02-29)The general solutions of a sum form functional equation containing two unknown mappings, without imposing any regularity condition on them, have been obtained. -
Hub-integrity of splitting graph and duplication of graph elements
(Işık University Press, 2016-01-08)The hub-integrity of a graph G = (V (G), E(G)) is denoted as HI(G) and defined by HI(G) = min{|S| + m(G ? S), S is a hub set of G}, where m(G ? S) is the order of a maximum component of G ? S. In this paper, we discuss ... -
Existence of positive solutions for a coupled system of higher order fractional boundary value problems
(Işık University Press, 2016)The aim of this paper is to establish the existence of at least one positive solution for a coupled system of higher order two-point fractional order boundary value problems under suitable conditions. The approach is based ... -
Solving fractional-order competitive lotka-volterra model by nsfd schemes
(Işık University Press, 2016-03-23)In this paper, we introduce fractional-order into a model competitive LotkaVolterra prey-predator system. We will discuss the stability analysis of this fractional system. The non-standard finite difference (NSFD) scheme ... -
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 ... -
Antimagic labeling of the union of subdivided stars
(Işık University Press, 2016-02-22)Enomoto et al. (1998) defined the concept of a super (a, 0)-edge-antimagic total labeling and proposed the conjecture that every tree is a super (a, 0)-edge-antimagic total labeling. In support of this conjecture, the ... -
Existence and uniqueness of tripled fixed points for mixed monotone operators with perturbations and application
(Işık University Press, 2016)In this article, we get the existence and uniqueness of tripled fixed points without assuming the operator to be compact or continuous, which extends the existing corresponding results. As applications, we utilize the ... -
A weighted goal programming approach to fuzzy linear regression with quasi type-2 fuzzy input-output data
(Işık University Press, 2016)This study attempts to develop a regression model when both input data and output data are quasi type-2 fuzzy numbers. To estimate the crisp parameters of the regression model, a linear programming model is proposed based ... -
Some results on generalized toeplitz operator on generalized hardy space
(Işık University Press, 2016)In this paper, we define and study some properties of the generalized Hardy space HF,2, where F is an injective linear transform from Lp (?) into Lp (?) and ? is the unit circle in the complex plane C. Also we introduce ... -
Inextensible flows of curves in the equiform geometry of the pseudo-Galilean space G13
(Işık University Press, 2016)In this paper, we study inextensible flows of curves in 3-dimensional pseudoGalilean space. We give necessary and sufficient conditions for inextensible flows of curves according to equiform geometry in pseudo-Galilean space. -
Existence and nonexistence of positive solutions for a n-th order three-point boundary value problem
(Işık University Press, 2016-02-04)The purpose of this paper is to establish some results on the existence and nonexistence of positive solutions for a type of nonlinear n-th order three-point boundary value problems. The main tool is a fixed point theorem ... -
On coincidence and common fixed point of six maps satisfying f-contractions
(Işık University Press, 2016)Coincidence and common fixed point of six self maps satisfying F-contractions are established via common limit in the range property without exploiting the notion of continuity or containment of range space of involved ...
