Tail spaces estimates on Hamming cube and Bernstein--Markov inequality

Abstract: This note contains some estimates for tail spaces on Hamming cube. We use analytic paraproduct operator for that purpose. We also show several types of Bernstein--Markov inequalities for Banach space valued functions on Hamming cube. Here the novelty is in getting rid of some irritating logarithms and in proving Bernstein--Markov inequalities for $|\nabla f|_X$ rather than for $\Delta^{1/2} f$ for $X$ valued polynomials on Hamming cube.
