Y -cone metric spaces and coupled common fixed point results with application to integral equation
(Işık University Press, 2022)This paper acquaints with a concept of Y -cone metric space and to study some topological properties of Y -cone metric space. We prove the coupled common fixed point results for mixed weakly monotone map in ordered Y -cone ... -
Approximate fixed point property in IFNS
(Işık University Press, 2022)In this paper, we define concept of approximate fixed point property of a function and a set in intuitionistic fuzzy normed space. Furthermore, we give intuitionistic fuzzy version of some class of maps used in fixed point ... -
Nonstandard finite difference schemes with application to biological models
(Işık University Press, 2022)This paper deals with the construction of nonstandard finite difference methods for solving a specific Rosenzweig-MacArthur predator-prey model. The reorganization of the denominator of the discrete derivatives and nonlocal ... -
Signed total double Roman dominatıon numbers in digraphs
(Işık University Press, 2022)Let D = (V, A) be a finite simple digraph. A signed total double Roman dominating function (STDRD-function) on the digraph D is a function f : V (D) ? {?1, 1, 2, 3} satisfying the following conditions: (i) P x?N?(v) f(x) ... -
Central derivation of some classes of Leibniz algebras
(Işık University Press, 2022)In this study, we deal with central derivation of finite low dimensional Leibniz algebras. We provide some properties of the central derivation algebras. Description of the central derivation algebras, with their dimensions, ... -
Some inequalities for the graph energy of distance Laplacian matrix
(Işık University Press, 2022)In this paper, the distance laplacian energy for distance matrix is examined. Some bounds for the laplacian eigenvalues of distance matrix are expanded including the distances, the vertices and the edges. Indeed, different ... -
The bounds for the largest eigenvalues of Fibonacci-sum and Lucas-sum graphs
(Işık University Press, 2022)In this paper, we first get the degree of each point in Lucas-sum graph based on Lucas numbers. After that, we obtain lower and upper bounds for the largest eigenvalues ? and µ of the adjacency matrices of Fibonacci-sum ... -
Almost unbiased ridge estimator in the zero-inated Poisson regression model
(Işık University Press, 2022)The zero-inflated Poisson regression (ZIP) model is a very popular model for count data that have extra zeros. In some situations, the count data are correlated and so multicollinearity exists among the explanatory variables. ... -
Mathematical model for the dispersion of toxicity through commuters
(Işık University Press, 2022)In the proposed paper, we consider three types of vehicle. One is those vehicles which are used for personal purposes called private vehicles. Second is for public transportation named as public vehicles. Third one is used ... -
Extending the applicability of a fourth-order method under Lipschitz continuous derivative in Banach spaces
(Işık University Press, 2022)We extend the applicability of a fourth-order convergent nonlinear system solver by providing its local convergence analysis under Lipschitz continuous Fréchet derivative in Banach spaces. Our analysis only uses the ... -
Color Laplacian energy of some cluster graphs
(Işık University Press, 2022)The color energy of a graph G is defined as the sum of the absolute values of the color eigenvalues of G. The graphs with large number of edges are referred as cluster graphs. Cluster graphs are obtained from complete ... -

L(t, 1)-colouring of graphs
(Işık University Press, 2022)One of the most famous applications of Graph Theory is in the field of Channel Assignment Problems. There are varieties of graph colouring concepts that are used for different requirements of frequency assignments in ... -
Some incomplete Riemann-Liouville fractional derivative operators
(Işık University Press, 2022)Several investigations were done by many researchers on extended fractional derivatives operators using different kinds of extended Beta functions (see, e.g.,([4],[7],[8],[18],[20]), and references therein). In this sequel, ... -
Solution of the two-dimensional telegraph equation via the local radial basis functions method
(Işık University Press, 2022)In the present study, we utilize the local meshless method for solving second order hyperbolic partial differential equation in two dimensions. First we apply the Crank-Nicolson difference scheme for the time derivative ... -
DNA Intuitionistic fuzzy turing machine
(Işık University Press, 2022)The restriction enzymes of bacteria are used to cut and insert the two strands of double-stranded DNA at different positions that cause overhangs of single stranded DNA. We developed an encoding transition table of an ... -
