Approximation theory. Korovkin type approximation theorems are practical tools to check whether a given sequence (A n) n≥1 of positive linear operators on C[a, b] of all continuous functions on the real interval [a, b] is an approximation process. That is, these theorems present a variety of test functions which provide that the approximation property holds on the whole space if it holds for Korovkin-type theorem which is one of the fundamental methods in approximation theory to describe uniform convergence of any sequence of positive linear operators is discussed on weighted L p spaces, 1 ≤ p theorems by means of 풜-summability which is a stronger convergence
sequence of positive linear operators that map C(Ω) into itself. We establish two Korovkin-type theorems in which the limit of the sequence of operators is not necessarily the identity. 1.

Abstract. This paper is devoted to studying weighted A-statistical convergence and statistical weighted A-summability of fuzzy sequences and their representations of sequences of λ-levels, which are obtain necessary and sufficient conditions for the matrix A to be weighted fuzzy regular and derive some inclusion relations concerning these newly proposed :// of Korovkin type theorems is really huge, a search on Google oﬀering more t results. However, except for Theorem in the paper of Bauer , the extension of this theory beyond the framework of linear functional analysis remained largely unexplored.

Lecture Notes in Mathematics, vol The Korovkin theorems are simple yet powerful tools for deciding whether a given sequence of positive linear operators on or is an approximation process.
Furthermore, they have been the source of a considerable amount of research in several other fields of mathematics (cf. Korovkin-type approximation theory).

WULBERT Department of Mathematics^ University of Washington, Seattle, Washington I. INTRODUCTION AND NOTATION LetL, denote a sequence of operators defined on C[0,1] (C^, respectively).
Originating from Korovkin's theorems (cf. Korovkin theorems), this theory consists of a collection of results whose main objective is to investigate under what circumstances the convergence of a (particular) sequence (more generally, net) of linear operators acting on a topological vector space is, in fact, a consequence of its convergence on special (possibly finite) ://.
In this paper, we propose to introduce a new Λ 2-weighted statistical upon this definition, we prove some Korovkin type theorems. We also find the rate of the convergence for this kind of weighted statistical convergence and derive some Voronovskaya type ://In particular,\ud we show that, if M is a subset of C0 (X) that separates the\ud points of X and if f0 in C0(X) is strictly positive, then\ud f0,f 0 M, f0 M2 is a Korovkin set in C0(X).\ud \ud This result is very useful because it furnishes a simple way to\ud construct Korovkin sets, but in addition, as we show in Section 9,\ud it turns out JOURNAL OF APPROXIMATION THE () Korovkin Closures for Positive Linear Operators KLAUS DONNER Mathematisches Institut der Universit Erlangen-Nurnberg, D Ericingen, West Germany Communicated by G.
