摘要：
Five interesting theorems of Konyushkov giving estimations for the best approximation in terms of the coefficients of a Fourier series are generalized or extended to the cases when the monotone or quasi-monotone coefficients are replaced by sequences of rest bounded variation of coefficients. © 2005 Akadémiai Kiadó, Budapest.
