Total roman domination number of graphs
(Işık University Press, 2022)In this paper a characterization of minimal total roman dominating functions has been proved. It has also been proved that if v is a pendant vertex and its neighbor u is not a pendant vertex then f(v) = 0 or 1 for any ... -
Fuzzy essential submodules with respect to an arbitrary fuzzy submodule
(Işık University Press, 2022)In this paper, we extend the concepts of a fuzzy essential submodule and a fuzzy complement submodule to the concepts of fuzzy essential submodule with respect to an arbitrary fuzzy submodule and fuzzy complement submodule ... -
The role of interior and closure operator in medical applications
(Işık University Press, 2022)In this paper, we consider the interior and closure operator as topological tools to apply in divisor cordial labeling. We investigate the properties related to the path with certain examples in a divisor cordial graphic ... -
Self-localized soliton solutions of the nonlinear quantum harmonic oscillator
(Işık University Press, 2022)We analyze the existences, properties and stabilities of the self-localized solutions of the nonlinear quantum harmonic oscillator (NQHO) using spectral renormalization method (SRM). We show that self-localized single and ... -
Some summation theorems for appell function of first kind having arguments ± 1

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, ... -
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 ... -
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) ... -
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 ... -

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. ...
