Partial sums of the Gaussian q-binomial coefficients, their reciprocals, square and squared reciprocals with applications
(Univ Miskolc Inst Math, 2019)In this paper, we shall derive formulae for partial sums of the Gaussian q-binomial coefficients, their reciprocals, squares and squared reciprocals. To prove the claimed results, we use q-calculus. As applications of our ... -
Suzuki Type Fixed Point Result for Rational theta-Contraction on Complete Metric Spaces
(Southeast Asian Mathematical Soc-Seams, 2019)In this paper, we present a new approach to fixed point theorems for single valued contraction mappings defined on complete metric spaces. We introduce a new concept called Suzuki type rational theta*-contraction and prove ... -
Parametric generalization of Baskakov operators
(Univ Osijek, Dept Mathematics, 2019)Herein we propose a non-negative real parametric generalization of Baskakov operators and call them alpha-Baskakov operators. We show that alpha-Baskakov operators can be expressed in terms of divided differences. Then, ... -
On two types almost (α,F_{d})-contractions on quasi metric space
(Ankara Univ, Fac Sci, 2019)In this paper, first we introduce two new types almost contractions on quasi metric space named as almost (alpha, F-d)-contraction of type (x) and of type (y). Then, taking into account both left and right completeness of ... -
On some approximation properties of the Gauss-Weierstrass operators
(Ankara Univ, Fac Sci, 2019)In this paper, we present some approximation properties of the Gauss-Weierstrass operators in exponential weighted spaces including norm convergence of them and Voronovskaya and quantitative Voronovskaya-type theorems. -
Approximation by a Generalization of the Jakimovski-Leviatan Operators
(Univ Nis, Fac Sci Math, 2019)In this paper, we introduce a Kantorovich type generalization of Jakimovski-Leviatan operators constructed by A. Jakimovski and D. Leviatan (1969) and the theorems on convergence and the degree of convergence are established. ... -

(Univ Prishtines, 2019)In this paper, we introduce a generalization of M-series by using the extended beta function. We also obtain its certain properties such as integral representations, derivative formulas, fractional integral and derivative ... -
Quantitative Voronovskaya Type Theorems For A General Sequence of Linear Positive Operators
(Univ Nis, Fac Sci Math, 2019)The present paper deal with the obtaining quantitative form of the results presented Butzer & Karsli [1]. That is, we prove quantitative simultaneous results by general sequence of positive linear operators which are valid ... -
Tauberian theorems for the weighted mean method of summability of integrals
(Amer Inst Physics, 2019)Let q be a positive weight function on R+ := [0, infinity) which is integrable in Lebesgue's sense over every finite interval (0, x) for 0 < x < infinity, in symbol: q is an element of L-loc(1)(R+) such that Q(x) := ... -
Almost Picard Operators
(Amer Inst Physics, 2019)The concept of Picard operator is one of the most important concept of fixed point theory. As known, a self mapping T of a metric space X is called Picard operator (PO) if it has unique fixed point and every Picard iteration ... -

(Springer Basel Ag, 2019)In this paper a comprehensive analysis of the Horadam quaternion zeros for some new types of bivariate quadratic quaternion polynomial equations is presented. -
Approximation properties of Szasz-Mirakyan operators preserving exponential functions
(Springer, 2019)This paper is a natural continuation of Acar et al. (Mediterr J Math 14:6, 2017, 10.1007/s00009-016-0804-7) where Szasz-Mirakyan operators preserving exponential functions are defined. As a first result, we show that the ... -
