A method for the proof of analogues of the classical Bernstein, Riesz and Boas inequalities for differentiation and difference operators defined by means of multipliers in terms of the Fourier-Dunkl transform is developed. This method is based on Civin-type interpolation formulae. Some of the inequalities obtained are sharp in the uniform norm. Bibliography: 42 titles.
Keywords: Bernstein, Riesz, and Boas inequalities, Dunkl operator
Mots-clés : sharp constant.
