ApproximationAbstract
The purpose of this paper is present a brief survey of know on estimates the rate for best approximation of unbounded functions by suitable trigonometric polynomials of one variable in weighted space\ L_{p,\alpha}(X). Moreover two theorems (3) and (4) concerning the rate of trigonometric approximation of f^{(k)} with k non-integer in L_{p,\alpha}(X).Downloads
