Selfadjoint extensions of a singular multipoint differential operator of first order
(2013)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 ... -
Some results for max-product operators via power series method
(Univerzita Komenskeho, 2018)In this paper, we obtain an approximation theorem by max-product operators with the use of power series method which is more effective than ordinary convergence and includes both Abel and Borel methods. We also estimate ... -
A trace formula for discontinuous eigenvalue problem
(University of Nis, 2017)In this paper, we deal with a Sturm-Liouville problem which has discontinuity at one point and contains an eigenparameter in a boundary condition. We obtain a regularized trace formula for the problem. © 2017, University ... -
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 ... -
Sturm-Liouville problem with moving discontinuity points
(Springer International Publishing, 2015)In this paper, we present a new discontinuous Sturm-Liouville problem with symmetrically located discontinuities which are defined depending on a parameter in the neighborhood of an interior point in the interval. Also the ... -
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. -
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 ... -
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 ... -
Some results on uniform statistical cluster points
(TUBİTAK, 2017)In this paper, we present some results linking the uniform statistical limit superior and inferior, almost convergence and uniform statistical convergence of a sequence. We also study the relationship between the set of ... -
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 ... -
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. ... -
Symmetry in complex contact manifolds
(Hitit Üniversitesi Fen Bilimleri Enstitüsü, 2017)Takahashi defined local φ-symmetry for Sasaki-an manifolds by the curvature condition that (()( , ) , )0gR Y ZWTX∇=0 for all horizontal vector fields ,,, ,X Y ZWT ([12]). There are two generalizations ... -
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 ...
