Symmetric (f, g) Bi-Derivations Of Lattices
(Util Math Publ Inc, 2015)In this paper as a generalization of symmetric bi-derivations and symmetric f bi-derivations of a lattice, we introduce the notion of symmetric (f, g) bi-derivations of a lattice. If the function g is equal to the function ... -
On Pointwise Convergence of q-Bernstein Operators and Their q-Derivatives
(Taylor & Francis Inc, 2015)Pointwise convergence of q-Bernstein polynomials and their q-derivatives in the case of 0 < q < 1 is discussed. We study quantitative Voronovskaya type results for q-Bernstein polynomials and their q-derivatives. These ... -
A note on maximal commutators and commutators of maximal functions
(Math Soc Japan, 2015)In this paper maximal commutators and commutators of maximal functions with functions of bounded mean oscillation are investigated. New pointwise estimates for these operators are proved. -
A New Approach to Caristi's Fixed Point Theorem on Non-Archimedean Fuzzy Metric Spaces
(Univ Sistan & Baluchestan, 2015)In the present paper, we give a new approach to Caristi's fixed point theorem on non-Archimedean fuzzy metric spaces. For this we define an ordinary metric d using the non-Archimedean fuzzy metric M on a nonempty set X and ... -
On Generalized Timelike Mannheim Curves in Minkowski Space-time
(Taylor & Francis Ltd, 2015)In Minkowski space-time, timelike generalized Mannheim curves are studied by Akyigit and et al in [1]. In that paper, the authors take the Mannheim mate alpha* of the timelike curve a as a timelike curve in Minkowski ... -
The Lehmer matrix with recursive factorial entries
(Academic Publication Council, 2015)A generalized Lehmer matrix with recursive entries from Kilic et al. (2010b) is further generalized, introducing three additional parameters and taking recursive factorials instead of a term. Certain formulae are derived ... -
Simultaneous approximation with generalized Durrmeyer operators
(Elsevier Science Inc, 2015)The aim of this paper is to obtain some convergence properties of generalized sequences of Ibragimov-Gadjiev-Durrmeyer operators which are a wide class of linear positive operators including many well known linear positive ... -
On A New Class Of Multivalued Weakly Picard Operators On Complete Metric Spaces
(Mathematical Soc Rep China, 2015)In the present paper, the concept of nonlinear F-contraction for multivalued mappings in metric spaces is introduced and considering the new proof technique, which was used for single valued maps by Wardowski [D. Wardowski, ... -
Asymptotic Formulas for Generalized Szasz-Mirakyan Operators
(Elsevier Science Inc, 2015)In the present paper, we consider the general Szasz-Mirakyan operators and investigate their asymptotic behaviours. We obtain quantitative Voronovskaya and quantitative Gruss type Voronovskaya theorems using the weighted ... -
Recent developments about multivalued weakly Picard operators
(Belgian Mathematical Soc Triomphe, 2015)In the present paper, considering a recent technique, which is used by Wardowski [24] for fixed points of single-valued mappings, we give a new and general class of multivalued weakly Picard operators on complete metric ... -
A curious matrix-sum identity and certain finite sums identities
(World Scientific Publ Co Pte Ltd, 2015)In this paper, we consider two generalized binary sequences and then give a generalization of a matrix equality proposed as an advanced problem. Then, we derive new certain finite sums including the generalized binary ... -
A generalization of Jam's operators
(Elsevier Science Inc, 2015)In this paper, we introduce a generalization of Jams operators based on a function rho. We examine convergence properties of such operators and prove a Voronovskaya type result. (C) 2015 Elsevier Inc. All rights reserved. -
Split Fibonacci and Lucas Octonions
(Springer Basel Ag, 2015)In this paper, split Fibonacci and Lucas octonions are proposed and their some properties and relations are obtained. -
Generalized Bertrand curves with timelike (1,3)-normal plane in Minkowski space-time
(Academic Publication Council, 2015)In this paper, we reconsider the (1,3)-Bertrand curves with respect to the casual characters of (1,3)-normal plane which is a plane spanned by the principal normal and the second binormal vector fields of the given curve. ... -
On Approximation Properties of a New Type of Bernstein-Durrmeyer Operators
(Walter De Gruyter Gmbh, 2015)The present paper deals with a new type of Bernstein-Durrmeyer operators on mobile interval. First, we represent the operators in terms of hypergeometric series. We also establish local and global approximation results for ... -
Reverse Hardy-type inequalities for supremal operators with measures
(Element, 2015)In this paper we characterize the validity of the inequalities parallel to g parallel to(p,(a, b),lambda) <= c parallel to u(x)parallel to g parallel to(infinity,(x,b),mu) parallel to(q,(a,b),nu) and parallel to g parallel ... -
Generalized Null Bertrand Curves In Minkowski Space-Time
(Univ Al I Cuza, Fac Math, 2014)COKEN and CIFTCI proved that a null Cartan curve in Minkowski space-time E-1(4) is a null Bertrand curve if and only if k(2) is nonzero constant and k(3) is zero. That is, the null curve with non-zero curvature k(3) is not ... -
