On the order of local approximation of functions by trigonometric polynomials that are partial sums of averaging operators
We study the order of polynomial approximations of periodic functions on intervals which are internal with respect to the main interval of periodicity and on which these functions are sufficiently smooth. The estimates obtained contain parameters which characterize the smoothness and alternation of...
