Functions, represented as trigonometric series with general monotone according subsequences Fourier coefficients, are considered in the article. For such functions estimates of the norm and modulus of smoothness are given.
Keywords: general monotone subsequences, moduli of smoothnes.
Mots-clés : Fourier serie, coefficient
