Abstract Korovkin theory in modular spaces in the sense of power series method
(2018)In this paper, using the power series method we obtain an abstract Korovkin type approximation theorem for a sequence of positive linear operators dened on modular spaces. -
Approximation by positive linear operators in modular spaces by power series method
(Birkhauser Verlag AG, 2017)In the present paper, we study the problem of approximation to a function by means of positive linear operators in modular spaces in the sense of power series method. Indeed, in order to get stronger results than the ... -
Arbitrarily long factorizations in mapping class groups
(Oxford University Press, 2015)Abstract. On a compact oriented surface of genus g with n ≥ 1 boundary components, δ1, δ2, . . . , δn, we consider positive factorizations of the boundary multitwist tδ1 tδ2 · · ·tδn , where tδi is the positive Dehn twist ... -
The Arzelà-Ascoli theorem by means of ideal convergence
(De Gruyter, 2018)In this paper, using the concept of ideal convergence, which extends the idea of ordinary convergence and statistical convergence, we are concerned with the I-uniform convergence and the I-pointwise convergence of sequences ... -
Computation of Eigenfunctions of Nonlinear Boundary-Value -Transmission Problems by Developing Some Approximate Techniques
(SOC PARANAENSE MATEMATICA, 2023)In this study, we investigate a boundary value problem for nonlinear Sturm-Liouville equations with additional transmission conditions at one interior singular point. Known numerical methods are intended for solving initial ... -
First order self-adjoint multipoint quasi-differential operators
(TÜBİTAK, 2018)In this paper, using the Calkin-Gorbachuk method, the general form of all self-adjoint operators generated by first order linear singular multipoint quasi-differential expressions in the direct sum of weighted Hilbert ... -
Generalized differential transformation method for solving two-interval Weber equation subject to transmission conditions
(KARAGANDA STATE UNIV, 2023)The main goal of this study is to adapt the classical differential transformation method to solve new types of boundary value problems. The advantage of this method lies in its simplicity, since there is no need for ... -
Inclusion results on statistical cluster points
(Springer Netherlands, 2016)We study the concepts of statistical cluster points and statistical core of a sequence for Aλ methods defined by deleting some rows from a nonnegative regular matrix A. We also relate Aλ-statistical convergence to ... -
Korovkin type approximation theorems in weighted spaces via power series method
(Element D.O.O., 2018)In this paper we consider power series method which is also member of the class of all continuous summability methods. We study a Korovkin type approximation theorem for a sequence of positive linear operators acting from ... -
Lightlike hypersurfaces of a semi-riemannian product manifold and quarter-symmetric nonmetric connections
(Hindawi Publishing Corporation, 2012)We study lightlike hypersurfaces of a semi-Riemannian product manifold. We introduce a class of lightlike hypersurfaces called screen semi-invariant lightlike hypersurfaces and radical anti-invariant lightlike hypersurfaces. ... -
Maximal sectorial differential operators for first order
(2015)In this study, the maximal sectorial linear relations are described. Then, the discreteness of the spectrum of the linear maximal sectorial operators and asymptotical behavior of the eigenvalues of such operators in terms ... -
A New Treatment of the Decomposition Method for Nonclassical Boundary Value Problems
(Amer Scientific Publishers, 2018)In this work, we will adapt the Adomian Decomposition Method to nonclassical boundary value problems the main feature of which is the nature of the equations and the boundary conditions imposed. Namely, the boundary ... -
Normal extensions of a singular differential operator on the right semi-axis
(Eurasian Mathematical Journal, 2014)In this work, based on the method of Everitt-Zettl and using the Calkin-Gorbachuk method, all normal extensions of the minimal operator generated by a linear singular formally normal differential-operator expression of the ... -
Normal extensions of a singular multipoint differential operator of first order
(2012)Many problems arising in the modelling of processes of multi-particle quantum mechanics,in the quantum field theory,in the multipoint boundary value problems for the differential equations,in the physics of rigid bodies ... -
A note on the generalized Matsumoto relation
(TUBİTAK, 2017)We give an elementary proof of a relation, first discovered in its full generality by Korkmaz, in the mapping class group of a closed orientable surface. Our proof uses only the well-known relations between Dehn twists. © TÜBİTAK. -
On information geometrical structures
(Hitit Üniversitesi Fen Bilimleri Enstitüsü, 2017-11-18)Information geometry is a modern differential geometric approach to statistics, in particular theory of information. The main motivation for this expository survey article is the lack of compact material that mainly address ... -
On the spectrums of some class of selfadjoint singular differential operators
(Ankara University, 2016)Abstract. In this work, based on the Everitt-Zettl and Calkin-Gorbachuk methods in terms of boundary values all selfadjoint extensions of the minimal operator generated by some linear singular multipoint symmetric ... -
Open book decompositions of links of quotient surface singularities and support genus problem
(American Institute of Mathematical Sciences, 2019)Abstract: In this paper we write explicitly the open book decompositions of links of quotient surface singularities supporting the corresponding unique Milnor fillable contact structure. The page-genus of these Milnor open ... -
The regularized trace of Sturm–Liouville problem with discontinuities at two points
(Taylor and Francis Ltd., 2017)In this paper, we obtain a regularized trace formula for a Sturm–Liouville problem which has two points of discontinuity and also contains an eigenparameter in a boundary condition. © 2016 Informa UK Limited, trading as ... -
