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 ...
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. ...
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 ...
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 ...
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 ...
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 ...
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.
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 ) ...
Combining genetic algorithm and Sinc-Galerkin method for solving an inverse diffusion problem
(Işık University Press, 2017)
A numerical approach combining the use of a genetic algorithm with the solution of the Sinc-Galerkin method is proposed for the determination of an unknown time-dependent diffusivity a(t) in an inverse diffusion problem ...
Common coupled fixed point theorem under weak ? ? ? contraction for hybrid pair of mappings with application
(Işık University Press, 2017)
We establish a common coupled fixed point theorem for hybrid pair of mappings under weak ? ? ? contraction on a non-complete metric space, which is not partially ordered. It is to be noted that to find coupled coincidence ...
