On the properties for families of function classes over harmonic intervals and their embedding relation with Besov spaces

The article is dedicated to the issues of studying the approximation of functions by trigonometric polynomials with a spectrum from special sets. In this paper, these special sets are harmonic intervals. To study the approximation of functions over harmonic intervals, families of function classes h...
