Abstract
Analogs of the Nikol’skii inequality in Lorentz–Zygmund spaces are obtained for functions of the form ∑nk=1ckφk, where {φk} is a finite orthonormal system in L2 bounded in L∞. No assumptions about smoothness of considered functions are required. Used technique relies only on the properties of Lorentz–Zygmund spaces and Fourier series map. In addition, real interpolation method is applied.
