Certain subclass of univalent functions associated with M–series based on q–derivative
(Işık University Press, 2021)By applying the q–derivative, M–series, convolution an subordination structures, we introduce a new subclass of univalent functions. For this subclass of functions, we obtain coefficient inequality, convexity and convolution ... 
On a fractional integral operator containing ψgeneralized Mittag Leffler function in its kernel and properties
(Işık University Press, 2021)This paper is devoted to the study of ψgeneralized MittagLeffler function associated with ψgeneralized beta function. We also obtain integral representations and other useful properties of it for example, Mellin transforms, ... 
Codes over the multiplicative hyperrings
(Işık University Press, 2021)Codes over hyperstructures have more codewords than codes over rings(or fields). It implies that they have higher rate than codes over rings (or fields). So, in this paper the codes over multiplicative hyperrings are ... 
Solution of partially singularly perturbed system of initial and boundary value problems using nonuniform Haar Wavelet
(Işık University Press, 2021)An efficient nonuniform Haar wavelet method is proposed for the numerical solution of system of first order linear partially singularly perturbed initial value problem on piecewise uniform Shishkin mesh and ρmesh. Further, ... 
Generalization of Randić energy and sumconnectivity energy
(Işık University Press, 2021)In this paper we define the generalization of Randić energy and sum connectivity energy of a graph. Then we obtain upper and lower bounds for E(Ars), generalization of Randić energy and sum connectivity energy of a graph. ... 
Approximation by LupaşStancu operators based on qinteger
(Işık University Press, 2021)The purpose of this paper is to introduce a Stancu type generalization of the Lupa¸s operators based on the qintegers. We investigate the rate of convergence of operators by mean of modulus of continuity and functions ... 
Effects of sinusoidal and nonsinusoidal temperature modulation in a triple diffusive convection
(Işık University Press, 2021)The Triple Diffusive convection with timedependent sinusoidal (cosine) and nonsinusoidal (square and triangular) temperature modulation is studied using linear and nonlinear analysis. The expression for Rayleigh number ... 
Group methods for second order delay differentşal equations
(Işık University Press, 2021)In this research paper, we obtain the equivalent symmetries of nonhomogeneous second order delay differential equations with variable coefficients. Group methods have been used to do this. The approach followed by us to ... 
Some new Hermite–Hadamard integral inequalities in multiplicative calculus
(Işık University Press, 2021)In this paper, we tend to establish some new Hermite–Hadamard type integral inequalities for multiplicatively convex function on coordinates and for product of two multiplicatively convex functions on coordinates. 
On generalization of explicit expressions of some hybrid Tricomi functions
(Işık University Press, 2021)In this paper, a general quadruple series identity is established. By using general quadruple series identity, a Laurent type hypergeometric generating relation is derived. Certain explicit expressions of some hybrid special ... 
Computing ve topological indices of Tickysim SpiNNaker Model
(Işık University Press, 2021)Topological parameters are employed to calculate the biological activity, thermodynamic properties, chemical reactivity and physical features of different structures, since various studies show a strong bond between the ... 
Disjunctive total domination in some graphs derived from the subdivision graph
(Işık University Press, 2021)For a set S ⊆ V (G), if every vertex has a neighbor in S or has at least two vertices in S at distance two from it, then the set S is a disjunctive total dominating set of G. The minimum cardinality of such a set is equal ...
