F-index for fuzzy graph with application
(Işık University Press, 2023-04)Different types of topological index of a graph have many applications and many results are available for crisp graphs. But in many practical applications it is seen that many situations cannot be modeled using crisp graphs. ... -
Face antimgaic labeling of double duplication for some special graphs
(Işık University Press, 2023-10)The main objective of the paper is to determine (a, d)? face antimagic labeling for the double duplication of all vertices by edges of ladder, tadpole and m-copies of path graphs. Also, if a graph G is (a, d)? face antimagic ... -
FCSTP with possibility and expected value approaches in hybrid uncertain environments
(Işık University Press, 2021)The objective of this investigation is to formulate a fixed charge (FC) solid transportation problem (STP) under a hybrid uncertain environment where both fuzziness and roughness coexist. A fuzzy rough STP model is developed ... -
Fekete-Szegö inequality for analytic and bi-univalent functions subordinate to (p, q) −Lucas polynomials
(Işık University Press, 2021)In this paper, a subclass of analytic and bi-univalent functions by means of (p, q) − Lucas polynomials is introduced. Certain coefficients bounds for functions belonging to this subclass are obtained. Furthermore, the ... -
The Fekete-Szegö problems for a subclass of m-fold symmetric bi-univalent functions
(Işık University Press, 2021)In this paper, we investigate a new subclass P??? ?m(?, ?) of m-fold symmetric bi-univalent functions. Moreover, for functions of this subclass, we obtain the coefficient estimates of the Taylor-Maclaurin coefficients ... -
Fermatean fuzzy matrices
(Işık University Press, 2022)In this paper, we introduce the concept of Fermatean fuzzy matrices, which are direct extensions of an intuitionistic fuzzy matrices. Then we define some algebraic operations, such as max-min, min-max, complement, algebraic ... -
Fitted computational method for convection dominated diffusion equations with shift arguments
(Işık University Press, 2024-04)A time dependent singularly perturbed convection diffusion equation involving shift parameters are considered. The terms containing the shifts are treated using Taylor series approximation up to second order terms. Classical ... -

(Işık University Press, 2022)The aim of this paper is to present fitted non-polynomial spline method for singularly perturbed differential-difference equations with integral boundary condition. The stability and uniform convergence of the proposed ... -
A fixed point problem via simulation functions in incomplete metric spaces with its application
(Işık University Press, 2020)In this paper, firstly, we review the notion of the SO-complete metric spaces. This notion let us to consider some fixed point theorems for single-valued mappings in incomplete metric spaces. Secondly, as motivated by the ... -
