Necessary and sufficient conditions of belonging to the Besov–Potapov classes and Fourier coefficients with respect to multiplicative systems
R. N. Fadeev Saratov State University
Abstract:
In this paper we obtain necessary and sufficient conditions for a function to belong to the Besov–Potapov classes. Using functions with Fourier coefficients with respect to multiplicative systems from the class GM, we show the sharpness of some these results.
Key words:
multiplicative system, Besov–Potapov classes, generalized monotonicity, Hardy–Littlewood–Paley theorem.
