摘要：
In the present paper, we establish a theorem on best approximation of a function g is an element of B-q(lambda) (L-r) of its Fourier series. Our main theorem generalizes some known results of this direction of work. Thus, the results of [10], [26] and [27] become the particular case of our main Theorem 3.1.
