Abstract:
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, Fourier serie, coefficient, moduli of smoothnes.
