Webleading example is the Paley-Zygmund argument. Closely related examples include the Chung-Erd os inequality and even Cantelli’s inequality (which ips to an upper bound). The Cramer-Rao inequality rounds out the list. 1. Paley-Zygmund Argument Consider a nonnegative random variable X. It is natural to let EX define a WebApr 15, 2024 · Exercise 11 Let be the Littlewood-Paley square function. Show that the inequality that would imply by a duality argument is . and not as one could naively expect. Next, assume that holds and use it to prove the inequality above.

WebThis article studies Paley's theory for lacunary Fourier series on (nonabelian) discrete groups. The results unify and generalize the work of Rudin for abelian discrete groups and the work of Lust-Piquard and Pisier for operator valued functions, and provide new examples of Paley sequences and $\\Lambda(p)$ sets on free groups.

The results unify and generalize the work of Rudin ([32] Section 8) for abelian … WebIn this paper, we will prove a new discrete weighted Hardy’s type inequality with dif-ferent powers. Next, we will apply this inequality to prove that the forward and backward prop-agation properties (self-improving properties) for the general discrete class Bp,q of weights that satisfy the reverse H¨older inequality hold.
