On generalization of explicit expressions of some hybrid Tricomi functions
(Işık University Press, 2021)In this paper, a general quadruple series identity is established. By using general quadruple series identity, a Laurent type hypergeometric generating relation is derived. Certain explicit expressions of some hybrid special ... -
Computing ve topological indices of Tickysim SpiNNaker Model
(Işık University Press, 2021)Topological parameters are employed to calculate the biological activity, thermodynamic properties, chemical reactivity and physical features of different structures, since various studies show a strong bond between the ... -
Disjunctive total domination in some graphs derived from the subdivision graph
(Işık University Press, 2021)For a set S ⊆ V (G), if every vertex has a neighbor in S or has at least two vertices in S at distance two from it, then the set S is a disjunctive total dominating set of G. The minimum cardinality of such a set is equal ... -
Some operators on Pythagorean fuzzy soft matrices
(Işık University Press, 2021)In this paper, we define modal operators of Pythagorean fuzzy soft matrices and establish their algebraic properties. Also, we define implication operators on Pythagorean fuzzy soft matrices and discuss some properties on ... -
Analytic solution of nonlinear singular BVP with multi-order fractional derivatives in electrohydrodynamic flows
(Işık University Press, 2021)In this study, a power series formula is proposed in order to introduce a new innovated numerical method called a newly Power Series Method (NPSM), beside with a construction of its error bound, to obtain approximate ... -
Remarks on the multiplicative operations of intuitionistic fuzzy matrices
(Işık University Press, 2021)In this paper, using the definition of the multiplicative operations X? and X? of intuitionistic fuzzy matrices, we construct nA and A? of an intuitionistic fuzzy matrix A and establish their algebraic properties. Also, ... -
The non-homogeneous of semi-linear parabolic equation with integral conditions
(Işık University Press, 2021)In this paper we introduce another method to establish finite time blow-up. This method, introduce by Levine–Payne in the papers [3], [4] and is due to Levine (1973), uses the concavity of an auxiliary function I(t). -
Coeffıcient estimates for bi-univalent ma-minda type functions associated with q-derivative
(Işık University Press, 2021)In this article, we consider a new subclasses of analytic and bi-univalent functions associated with q-derivative in the open unit disk. We obtain coefficient bounds for the Taylor-Maclaurin coefficients |a2| and |a3| of ... -
An extension theorem on degree of approximation of fourier series by (E, q)B−mean
(Işık University Press, 2021)Now-a-days, approximation of functions have great importance in the field of science and engineering because of its wider applicability. It is observed that the determination of trigonometric approximation of functions in ... -
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 ... -

(Işık University Press, 2021)In this article, we introduce I− convergent triple sequence spaces 3SI (M) , 3SI0 (M), 3S I∞(M) with the help of a compact operator and an Orlicz function. We study some of their algebraic and topological properties like ... -
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 ... -
