Upper bounds for covering total double Roman domination
(Işık University Press, 2023-07)Let G = (V, E) be a finite simple graph where V = V (G) and E = E(G). Suppose that G has no isolated vertex. A covering total double Roman dominating function (CT DRD function) f of G is a total double Roman dominating ... -
Stable algorithm for the wave equation using finite difference method
(Işık University Press, 2023-07)The numerical solution of hyperbolic equations has shown instabilities in some studies (see [2]). In this paper, we use a trick to remedy the reasons for instabilities of particular example of hyperbolic equation, namely ... -
Certain topological indices and related polynomials for polysaccharides
(Işık University Press, 2023-07)A polysaccharide is a large molecule made of many smaller monosaccharides. Monosaccharides are simple sugars, like glucose. Special enzymes bind these small monomers together creating large sugar polymers or polysaccharides. ... -
Controllability of a semilinear neutral dynamic equation on time scales with impulses and nonlocal conditions
(Işık University Press, 2023-07)In this paper we consider a control system governed by a neutral differential equation on time scales with impulses and nonlocal conditions. We obtain conditions under which the system is approximately controllable, on one ... -
On the m-fold product of fractional operators
(Işık University Press, 2023-07)In this work, using the m-fold product of fractional integral and maximal operators, we prove that the boundedness of these fractional operators and their corresponding multilinear fractional operators under some conditions ... -
Identifying cyclic and (1 + 2v)-constacyclic codes over Z?[v]/ <v³ – 1> with Z?-linear codes
(Işık University Press, 2023-07)This paper studies cyclic and (1 + 2v)-constacyclic codes over the ring Z?[v]/<v³ – 1>. By introducing three different Gray maps, we show that the Gray images of cyclic codes are quasi-cyclic codes over Z? and that of (1 ... -
Optimal control of first-order undivided inclusions
(Işık University Press, 2023-07)The article is devoted to the optimization of first-order evolution inclusions (DFI) with undivided conditions. Optimality conditions are formulated in terms of locally adjoint mappings (LAMs). The construction of “duality ... -
Total absolute difference edge irregularity strength of some families of graphs
(Işık University Press, 2023-07)A total labeling ? is defined to be an edge irregular total absolute difference k-labeling of the graph G if for every two different edges e and f of G there is wt(e) ? wt(f) where weight of an edge e = xy is defined as ... -
Cubic pythagorean fuzzy linear spaces
(Işık University Press, 2023-07)Pythagorean fuzzy sets assist in handling more uncertain and vague data than fuzzy sets and intuitionistic fuzzy sets. The notion of cubic pythagorean fuzzy sets is defined by combining interval valued pythagorean fuzzy ... -
Hyper-connectivity index for fuzzy graph with application
(Işık University Press, 2023-07)Connectivity concept is one of the most important parameters in fuzzy graphs (FGs). The stability of a FG is dependent on the strength of connectedness between each pair of vertices. Depending on “strength of connectedness ... -

(Işık University Press, 2023-07)In this paper, the concepts of intuitionistic fuzzy translation to intuitionistic fuzzy subalgebras in BG-algebras are introduced. The notion of intuitionistic fuzzy extensions and intuitionistic fuzzy multiplications of ... -
New notions of triple ideal convergent on intuitionistic fuzzy normed spaces
(Işık University Press, 2023-07)In this paper, we introduce and study the notions of MI3(µ,v)(T), MI03(µ,v)(T), MI3(µ,v)(T, F) and MI03(µ,v)(T, F) for triple sequences in intuitionistic fuzzy normed space for the sequence. Furthermore, some topological ... -
A generalization of fixed point results in complex–valued quasi–partial b–metric space
(Işık University Press, 2023-07)The aim of this paper is to establish and prove several results on fixed point portrayed in complex valued metric spaces i.e. to bring in a new type of extended bmetric space, which we call complex–valued quasi–partial ... -
Solving fractional differential equations using fixed point results in generalized metric spaces of Perov’s type
(Işık University Press, 2022-07)In 1964, A. I. Perov generalized the Banach contraction principle introducing, following the work of ¯D. Kurepa, a new approach to fixed point problems, by defining generalized metric spaces (also known as vector valued ... -
Ideal and dot ideal of a PS algebra in picture fuzzy environment
(Işık University Press, 2023-07)In this paper, the notion of picture fuzzy ideal of a PS algebra is introduced as a generalization of fuzzy ideal of a PS algebra and some important results are explored in this regard. It is highlighted that the intersection ... -
A semi-parametric estimation of copula models based on moments method under right censoring
(Işık University Press, 2023-07)Based on the classical estimation method of moments, a new copula estimator was proposed for censored bivariate data. As theoretical results, general formulas were proved with analytical forms of the obtained estimators. ... -
