Characterizations for the family of functions classes {B^r_p,q,N} and their connection with Besov’s spaces

Characterizations for the family of functions classes {B^r_p,q,N} and their connection with Besov’s spaces

In this paper we define families of classes of functions related to best approximations in harmonic intervals. These families of function classes characterize the order of approximation of functions by trigonometric polynomials with a spectrum from harmonic intervals. The article contains an invest...
