Natural and conjugate mates of Frenet curves in three-dimensional Lie group
(Ankara Üniversitesi Fen Fakültesi, 2021-06-30)In this study, we introduce the natural mate and conjugate mate of a Frenet curve in a three dimensional Lie group G with bi-invariant metric. Also, we give some relationships between a Frenet curve and its natural ... -
New fuzzy differential subordinations
(Ankara Üniversitesi Fen Fakültesi, 2021-06-30)In this paper, some new fuzzy differential subordinations obtained by using the integral operator Im γ : An →An introduced in [13] are obtained. -
Nonparametric modeling via two-way mixed effects design
(Ankara Üniversitesi Fen Fakültesi, 2021-06-30)The classical F-test for testing the hypothesis of no fixed main effects in a mixed effects design is valid under the assumption of normality, symmetry and variance homogeneity of the error terms assumption. We consider ... -
On almost Hurewicz property in bitopological spaces
(Ankara Üniversitesi Fen Fakültesi, 2021-06-30)The purpose of this paper is to investigate properties and results of the almost Hurewicz property in bitopological spaces. We characterize this property using ( i , j ) - regular open sets and almost continuous ... -
On exponential type P-functions
(Ankara Üniversitesi Fen Fakültesi, 2021-06-30)In this paper, we introduce and study the concept of exponential type P-function and establish Hermite-Hadamard's inequalities for this type of functions. In addition, we obtain some new Hermite-Hadamard type inequalities ... -
On the lifts of F_{a}(5,1)-structure on tangent and cotangent bundle
(Ankara Üniversitesi Fen Fakültesi, 2021-06-30)This paper consist of three main sections. In the first part, we obtain the complete lifts of the F_{a}(5,1)-structure on tangent bundle. We have also obtained the integrability conditions by calculating the Nijenhuis ... -

(Ankara Üniversitesi Fen Fakültesi, 2021-06-30)Inverse nodal problem on Dirac operator is determination problem of the parameters in the boundary conditions, number m and potential function V by using a set of nodal points of a component of two component vector ... -
Pseudo pure-injective objects
(Ankara Üniversitesi Fen Fakültesi, 2021-06-30)We show that if M and N are pure essentially equivalent objects in a finitely accessible additive category A such that M is pseudo pure-N- injective and N is pseudo pure-M-injective, then M≅N. -
Set operators and associated functions
(Ankara Üniversitesi Fen Fakültesi, 2021-06-30)The study of two operators local function and the set operator ψ on the ideal topological spaces are likely to be same to the study of closure and interior operator of the topological spaces. However, they are not ... -

Univalence criteria of the certain integral operators
(Ankara Üniversitesi Fen Fakültesi, 2021-06-30)In this paper, we give some sufficient conditions for the univalence of some integral operators. For this, we use the Becker's and generalized version of the well known Ahlfor's and Becker's univalence criteria.
