Abstract:
Sufficient conditions for the weighted integrability of multiple multiplicative Fourier transforms of Bernstein–Szasz type involving integral moduli of continuity and of Zygmund type with an additional boundedness condition for ss fluctuations are given in the paper. The sharpness of Bernstein–Szasz type tests is proved under certain restrictions.
Keywords:
multiplicative Fourier transform, weighted integrability, function with bounded ss-fluctuation, Lipschitz classes.
