Multiple Fourier series for functions from a Zygmund class
S. L. Donskikh Lomonosov Moscow State University, Faculty of Mechanics and Mathematics
Abstract:
The paper concerns with necessary and sufficient conditions providing that a function of many variables with nonnegative trigonometric Fourier coefficients velongs to the big and small Zygmund classes. Earler, such a result was obtained by R. P. Boas in the
one-dimensional case and by V. Fulop in the two-dimensional case.
Key words:
functions of many variables, Fourier coefficients, Zygmund classes.
