Estimates for Piecewise Linear Approximation of Derivative Functions of Sobolev Classes

The article considers the problem of estimating the error in calculating the gradient of functions of Sobolev classes for piecewise linear approximation on triangulations. Traditionally, problems of this kind are considered for continuously differentiable functions. In this case, the corresponding e...
