Dynamics, control, stability, diffusion and synchronization of modified chaotic colpitts oscillator with triangular wave non-linearity
(Işık University Press, 2022-07)The purpose of this paper is to introduce a new chaotic oscillator. Although different chaotic systems have been formulated by earlier researchers, only a few chaotic systems exhibit chaotic behaviour. In this work, a new ... -
Boundary value problem of Caputo fractional differential equations of variable order
(Işık University Press, 2023-07)In this work, we investigate the existence, uniqueness and the stability of solutions to the boundary value problem (BVP) of Caputo fractional differential equations of variable order by converting it into an equivalent ... -
Application of neutrosophic Poisson probability distribution series for certain subclass of analytic univalent function
(Işık University Press, 2023-07)Necessary and sufficient conditions for neutrosophic Poisson probability distribution series to be in the classes Mn? (?) were derived by means of coefficient inequalities. The results obtained further strengthening the ... -
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 ... -
