The Error of Approximation of Differentiable Functions of Several Variables by Means of Interpolatory Shape-Preserving Operators

Abstract: 

The article deals with the estimation of the error of uniform approximation of differentiable functions of several variables with limited second derivations by means of linearinterpolation operators, which preserve the properties of positivity and convexity of approximated functions.
