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 operator GA-convex functions in Hilbert spaces
(American Institute of Physics Inc., 2018)In this paper, it is defined the operator GA-convex functions for continuous functions of self-adjoint operators in Hilbert spaces. And then it is obtained some new Hermite-Hadamard type inequalities for this class of ... -
On the spectrums of some class of selfadjoint singular differential operators

(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 ... -

Some results concerning the summability of spliced sequences
(TUBİTAK, 2016)A spliced sequence is formed by combining all of the terms of two or more convergent sequences, in their original order, into a new spliced sequence. In this paper replacing convergent sequences by bounded sequences, we ... -
