Preservation of the invariants of Lotka-Volterra equations by iterated deferred correction methods
(Işık University Press, 2021)In this paper we apply Kahan’s nonstandard discretization to three dimensional Lotka-Volterra equations in bi-Hamiltonian form. The periodicity of the solutions and all polynomial and non-polynomial invariants are well ... -
Fuzzy injective S-act on monoids
(Işık University Press, 2021)The fuzzy injectivity and their generalizations on R-modules were studied by many authors. It is well known that the act of semigroups or monoids is a generalization of R-modules, here we will define the fuzzy injective ... -
Fixed point theorems for multivalued wordowski type contractions in b-metric spaces with an application to integral inclusions
(Işık University Press, 2021)The aim of this work is to give some fixed point results for set valued Fcontractions combined with the concept of ?s-admissible in b-metric spaces. some consequences are established on b-metric spaces endowed with a partial ... -
Application of Laplace transform to cryptography using linear combination of functions
(Işık University Press, 2021)The strength of nations, organizations such as military, intelligence agency, hinges primarily on its ability to keep sensitive information secure from intruders. Today, cryptography is used to protect mobile communication, ... -
An efficient method for a class of integro-differential equations with a weakly singular kernel
(Işık University Press, 2021)In this work, a class of volterra integro-differential equation with a weakly singular kernel is discussed. The shifted Legendre Tau method is introduced for finding the unknown function. The proposed method is based on ... -
Regular filters of commutative BE-algebras
(Işık University Press, 2021)The concept of regular filters is introduced in commutative BE-algebras. The class of all regular filters of a commutative BE-algebra is characterized in terms of dual annihilators. Some equivalent conditions are derived ... -

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 ... -
Computing µ-values and pseudo-spectra for Airy Operators
(Işık University Press, 2021)Stability analysis play a vital role to design a linear feedback system in system theory. The stability of a feedback system is the direct measure of the roots of characteristic equation of transfer functions. The main ... -

(Işık University Press, 2021)The work addressed in this paper is the analytic investigation of the steady thin film flow of non-Newtonian Johnson-Segalman fluid on vertical cylinder for lifting and drainage problems. The arised equation in the ... -
On the connected detour monophonic number of a graph
(Işık University Press, 2021)For a connected graph G = (V, E) of order at least two, a connected detour monophonic set S of G is called a minimal connected detour monophonic set if no proper subset of S is a connected detour monophonic set of G. The ... -
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 ... -

Method based on quasi variable mesh for solution of system of second order boundary value problems with mixed boundary conditions
(Işık University Press, 2021)A new numerical method with third order accuracy is presented for the solution of nonlinear two point boundary value problems(BVPs) with mixed boundary conditions using quasi variable mesh. In case of uniform mesh, method ... -
On fuzzy topologies generated by fuzzy relations
(Işık University Press, 2021)In this paper, we have introduced a fuzzy topology generated by a fuzzy relation as a generalization of the corresponding concept given by Smithson and obtained sufficient conditions under which this fuzzy topology becomes ... -
Cm-supermagic labeling of friendship graphs
(Işık University Press, 2021)The friendship graph F?n is obtained by joining n copies of the cycle graph Cm with a common vertex. In this work, we investigate the Cm-supermagic labeling of friendship graphs. -
Radial basis function generated finite difference method for the solution of sinh-Gordon equation
(Işık University Press, 2021)Accuracy of radial basis functions (RBFs) is increased as the shape parameter decreases and produces an ill-conditioned system. To overcome such difficulty, the global stable computation with Gaussian radial basis function-QR ... -
