L(2, 1)-Labeling of trapezoid graphs
(Işık University Press, 2024-07)An L(2, 1)−labeling (L21L) of a graph G = (V, E) is an assignment f from the node-set V to the set {0, 1, 2, 3, . . .} so that adjoining nodes get numbers at least two apart, and nodes at distance two get different numbers. ... -
Revised interval ASM method for multi-objective interval transportation problems
(Işık University Press, 2024-07)In this paper, a revised version of interval ASM method is proposed for solving multi objective interval transportation problems without converting them to their crisp equivalent forms. Multi-objective transportation ... -
Kernel and k-Kernel Symmetric Intuitionistic Fuzzy Matrices
(Işık University Press, 2024-07)The idea of Kernel and k-Kernel Symmetric (k-KS) Intuitionistic Fuzzy Matrices (IFM) are introduced with an example. We present some basic results of Kernel symmetric matrices. We show that k-symmetric implies k-Kernel ... -
On the k-Mersenne and k-Mersenne-Lucas octonions
(Işık University Press, 2024-07)This paper aims to introduce the k-Mersenne and k-Mersenne-Lucas octonions. We investigate the algebraic properties of these octonions in closed form and give some well-known identities like Catalan identity, d’Ocagne ... -
New results on generalization of Jordan centralizers over matrix rings
(Işık University Press, 2024-07)This paper presents a study on Jordan maps over matrix rings with some functional equations related to additive maps on these rings. We first show that every Jordan left (right) centralizer over a matrix ring is a left ... -
Frictional contact problems involving p(x)-Laplacian-like operators
(Işık University Press, 2024-07)This article is dedicated to studying a class of frictional contact problems involving the p(x)-Laplacian-like operator, on a bounded domain Ω ⊆ R². Using an abstract Lagrange multiplier technique and the Schauder fixed ... -
Relatively prime inverse domination on vertex switching of some graphs
(Işık University Press, 2024-07)Let G = (V, E) be a non-trivial graph. A subset D of the vertex set V of a graph G is called a dominating set of G if every vertex in V − D is adjacent to a vertex in D. The domination number is the lowest cardinality of ... -
On I-convergence almost surely of complex uncertain sequences
(Işık University Press, 2024-07)In this paper, we explore the concepts of I-convergence almost surely and I*-convergence almost surely in complex uncertain theory and study some of their properties and identify the relationships between them. Also, we ... -
Impact of modulated magnetic field on the advent of ferroconvection in a permeable medium
(Işık University Press, 2024-07)The effect of time-periodic magnetic field modulation on the onset of ferroconvection in a magnetic fluid saturated densely packed porous medium is examined. In many systems, such as charges in electrostatic field and ... -
More on picture fuzzy sets and their properties
(Işık University Press, 2024-07)In this paper, some basic properties of the set of a picture fuzzy set truth values D* are studied. Also, using an adequate order ≤ of D*, some picture fuzzy sets operations are introduced by meaning a punctual order (point ... -

(Işık University Press, 2024-07)In this paper, modulus of continuity, second kind Chebyshev wavelet and Hölder class are studied. The moduli of continuity and approximations of functions whose second derivative belonging to H¨older class have been ... -
Absolute convergence with speed and matrix transforms
(Işık University Press, 2024-07)We define the notion of absolute convergence with speed, where the speed is defined by a monotonically increasing positive sequence λ. Also we present the notion of absolute λ-conservativity of a matrix, and the notion of ... -
Generation of graphs using hyper-edge replacement graph rewriting P system
(Işık University Press, 2024-07)Hyper-edge replacement graph grammar is considered a kernel in generating graphs and hypergraphs, and it has stood out enough to be noticed in recent years. George Paun proposed Membrane computing, frequently known as P ... -
