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 ... -
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 ... -
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 ... -
Denumerably many positive solutions for rl-fractional order bvp having denumerably many singularities
(Işık University Press, 2022)In this paper, we consider Riemann-Liouville two-point fractional order boundary value problem having denumerably many singularities and determined sufficient conditions for the existence of denumerably many positive ... -
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 ... -
Hub number of generalized middle graphs
(Işık University Press, 2022)A hub set in a graph G is a set S ? V (G) such that any two vertices outside S are connected by a path whose all internal vertices are members of S. The minimum cardinality of hub set is called hub number. In this paper, ... -
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 ... -
Coefficient estimates for new subclasses of meromorphic bi-univalent functions associated with linear operatör
(Işık University Press, 2022)In this paper, we define a new differential linear operator of meromorphic bi-univalent functions class ??, and obtain the estimates for the coefficients |b?| and |b?|. Further we pointed out several new or known consequences ... -
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 ... -
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. ... -
Cyclical nonlinear contractive mappings fixed point theorems with application to integral equations
(Işık University Press, 2022)In this paper, we present new nonlinear contractions based on altering distances and prove the existence and uniqueness of fixed points for cyclic operators. We prove here very interesting fixed point theorems in which we ... -
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, ... -
Minimal restrained monophonic sets in graphs
(Işık University Press, 2022)For a connected graph G = (V, E) of order at least two, a restrained monophonic set S of a graph G is a monophonic set such that either S = V or the subgraph induced by V ?S has no isolated vertices. The minimum cardinality ... -
Edge product cordial labeling of switching operation on some graphs
(Işık University Press, 2022)Here we discuss and prove that the graphs attained by switching of any vertex with degree two which is adjacent to a vertex with degree two in triangular snake Tm, switching of any vertex with degree one in path Pm for m ... -
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 ... -
Domination number of a bipartite semigraph when it is a cycle
(Işık University Press, 2022)Semigraph is a generalization of graph, with two or more vertices on edges which allows multiplicity in every concept of graph when it comes to semigraph. When number of vertices on the edges are restricted to two the ... -
Convergence analysis of picard-s hybrid iteration scheme for multi-valued map having a fixed point
(Işık University Press, 2022)In this paper, we define Picard-S hybrid iteration for a multi-valued mapping of T with an invariant point ? along with explanation that under certain conditions, this iteration gets converged to an invariant point ? ... -
Kn(?) is fully {P7, S4}-decomposable
(Işık University Press, 2022)Let Pk+1 denote a path of length k, Sm denote a star with m edges, and Kn(?) denote the complete multigraph on n vertices in which every pair of distinct vertices is joined by ? edges. In this paper, we have obtained the ... -
Topological indices of Sierpi?ski Gasket and Sierpi?ski Gasket Rhombus graphs
(Işık University Press, 2022)Sierpi?ski graphs S(n, k) were defined originally in 1997 by Sandi Klav?ar and Uroš Milutinovi?. In this paper atom bond connectivity index, fourth atom bond connectivity indices, geometric arithmetic index, fifth geometric ... -
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 ...
