Statistical Approximation of Positive Linear Operators
2014In this chapter, we present some Korovkin-type approximation theorems for functions of two variables via statistical convergence, A-statistical convergence, and statistical A-summability. We also study rates of A-statistical convergence of a double sequence of positive linear operators.

On Ritz Approximations for Positive Definite Operators [PDF]
, 2003 We present new bounds for the eigenvalues and eigenvectors of positive definite operators. An algorithm for the computation of rigorous bounds for finite- element approximations is outlined. An accuracy of these approximations is assessed on several model examples and compared with the existing bounds found in the literature.

Approximation of positive functions by linear positive polynomial operators
2012The class of continuous 2π-periodical functions f(x) which satisfy the inequality \( |f(x+h)+f(x-h)-2f(x)|\leq 2|h|^\alpha \,\,\,\,\, 0 < \alpha < 2 \)is denoted by Zα.
