The purpose of this paper is to introduce the new concept of weighted statistical convergence and strong weighted summability of order β for sequences of fuzzy numbers involving the ideas of difference operators and two sequences. p = (p n), q = (q n) of positive numbers, and establish the relationship between these notions. the degree of convergence of sequences of linear positive operators O. Shisha and B. Mond AEROSPACE RESEARCH LABORATORIES, WRIGHT-PATTERSON AIR FORCE BASE, OHIO.

Suppose that L is a linear operator from C[a, b] into C[a, b]. It is clear that if f ≥ 0 implies Lf ≥ 0, then the linear operator L is positive on C[a, b]. We denote the value of Lf at a point x ∈ [a, b] by L(f; x). The classical Korovkin approximation theorem states the following. In the present paper, we study a new type of Bernstein operators depending on the parameter λ ∈ [-1, 1]. The Kantorovich modification of these sequences of linear positive operators will be considered. A quantitative Voronovskaja type theorem by means of Ditzian-Totik modulus of smoothness is proved.

For positive operators the picture is even better. THEOREM Let T:E → F be a positive operator between two Riesz spaces, then the following are equivalent. 1. Operator T preserves 1-convergence; 2. Operator T preserves 2-convergence. Proof. Consider a positive operator T:E → F between two Riesz spaces. For this reason various ways of de ning rates of convergence in the A¡statistical sense are intro-duced in . In the present paper, using the concepts of , we study rates of A¡statistical convergence of sequences of positive linear operators mapping the weighted space C1 into the weighted space B2 where 1 and 2 are weight functions.

The study of linear positive operators is an area of mathematical studies with significant relevance to studies of computer-aided geometric design, numerical analysis, and differential equations. This book focuses on the convergence of linear positive operators in real and complex by:   DEVORE, Optimal convergence of positive linear operators in "Proceedings of the Conference on Constructive Theory of Functions," pp.Publishing house of the Hungarian Academy of Sciences," Budapest, Cited by: This book is a valuable resource for Graduate students and researchers interested in current techniques and methods within the theory of moments in linear positive operators and approximation theory.

Moments are essential to the convergence of a sequence of linear positive operators. The present paper deals with the modified positive linear operators that present a better degree of approximation than the original ones.

This new construction of operators. Statistical -convergence of positive linear operators. In this chapter we study quantitatively with rates the weak convergence of a sequence of finite positive measures to the unit measure.

Equivalently we study quantitatively the pointwise convergence of sequence of positive linear operators to the unit operator, all acting on continuous functions.

() doi/ Download Positive Operator Semigroups books, This book gives a gentle but up-to-date introduction into the theory of operator semigroups (or linear dynamical systems), which can be used with great success to describe the dynamics of complicated phenomena arising in many applications.

Positivity is a property which naturally appears in physical. For a sequence {L n} of positive linear operators on C (X), Korovkin first introduced the sufficient conditions for the uniform convergence of L n (f) to a function f by using the test function e i defined by e i (x) = x i (i = 0, 1, 2).

Later many researchers investigated these conditions for various operators defined on different spaces. convergence of positive operator semigroups 5 If (G, ) is a group (and thus, in particular, a semigroup), then a semigr oup representation (T t) t ∈ G on a.
