Some notes on lifts of the F((υ+1),λ²(υ-1))-structure on cotangent and tangent bundle
(Ankara Üniversitesi Fen Fakültesi, 2021-06-30)
The F^{v+1}-λ²F^{v-1}=0 structure (v≥3) have been studied by Kim J. B. K75. Later, Srivastava S.K studied on the complete lifts of (1,1) tensor field F satisfying structure F^{v+1}-λ²F^{v-1}=0 and extended in Mⁿ to cotangent ...
Existence and decay of solutions for a higher-order viscoelastic wave equation with logarithmic nonlinearity
(Ankara Üniversitesi Fen Fakültesi, 2021-06-30)
The main goal of this paper is to study for the local existence and decay estimates results for a high-order viscoelastic wave equation with logarithmic nonlinerity. We obtain several results: Firstly, by using Feado-Galerkin ...
A metric formula on a quotient space which is related to the sequence space Σ 2
(Ankara Üniversitesi Fen Fakültesi, 2021-06-30)
In this paper, we first define an equivalence relation on the sequence space

Deferred Nörlund statistical relative uniform convergence and Korovkin-type approximation theorem
(Ankara Üniversitesi Fen Fakültesi, 2021-06-30)
In this paper, we define the concept of statistical relative uniform convergence of the deferred Nörlund mean and we prove a general Korovkin-type approximation theorem by using this convergence method. As an application, ...
The uniform convergence of Fourier series expansions of a Sturm-Liouville problem with boundary condition which contains the eigenparameter
(Ankara Üniversitesi Fen Fakültesi, 2021-06-30)
This paper is devoted to investigating the uniform convergence conditions of Fourier series expansions of continuous functions in terms of eigenfunctions of a Sturm-Liouville problem with eigenparameter in one of the ...
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 ...
Some properties of a new class of analytic functions defined via Rodrigues formula
(Ankara Üniversitesi Fen Fakültesi, 2021-06-30)
In this paper, we introduce and study the new family of analytic functions via Rodrigues formula. Some main properties, the generating function, various recurrence relations and differential properties of these functions ...
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.
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.
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.
