Inequalities of Calderon-Zygmund Type for Trigonometric Polynomials

abstract:
We give a unified approach to inequalities of Calderon--Zygmund type for trigonometric polynomials of several variables based on the Fourier analytic methods. Sharp results are achieved for the full range of admissible parameters $~p,~ 0
