Approximation of Unbounded Functions by Linear Positive Operators [PDF]
Mathematische Nachrichten, 1996 AbstractA unified class of linear positive operators has been defined. Using these operators some approximation estimates have been obtained for unbounded functions. For particular linear positive operators these results sharpen and improve the earlier estimates due to Fuhua Cheng (J. Approx. Theory, 1984) and Xiehua Sun (J. Approx. Theory, 1988).

Statistical rates in approximation by positive linear operators [PDF]
Miskolc Mathematical Notes, 2011 This study is the continuation of our former work [O. Duman and E. Erkus,, Comput. Math. Appl. 52 (2006) 967-974] in which we obtained a statistical Korovkin-type approximation theorem for a sequence of positive linear operators defined on the space of all real-valued continuous and 2 pi periodic functions on the real m-dimensional space. In this paper,

Quantitative estimates for L approximation with positive linear operators [PDF]
Journal of Approximation Theory, 1983 AbstractQuantitative estimates for approximation with positive linear operators are derived. The results are in the same vein as recent results of Berens and DeVore. Two examples are provided.

Caputo fractional approximation by sublinear operators [PDF]
Journal of Numerical Analysis and Approximation Theory, 2018 Here we consider the approximation of functions by sublinear positive operators with applications to a big variety of Max-Product operators under Caputo fractional differentiability. Our study is based on our general fractional results about positive

Positively p-nuclear operators, positively p-integral operators and approximation properties [PDF]
Positivity, 2022 In the present paper, we introduce and investigate a new class of positively $p$-nuclear operators that are positive analogues of right $p$-nuclear operators. One of our main results establishes an identification of the dual space of positively $p$-nuclear operators with the class of positive $p$-majorizing operators that is a dual notion of positive ...

On New Classes of Stancu-Kantorovich-Type Operators
Mathematics, 2021 The present paper introduces new classes of Stancu–Kantorovich operators constructed in the King sense. For these classes of operators, we establish some convergence results, error estimations theorems and graphical properties of approximation for the ...
