On the optimal $L_{p}$ - $L_{4}$ Khintchine inequality

Adam Barański, Daniel Murawski, Piotr Nayar +1

We derive optimal dimension independent constants in the classical Khintchine inequality between the $p$ th and fourth moment for $p \geq 4$ . As an application we deduce stability est…

Comparing moments of real log-concave random variables

Daniel Murawski

We show that for every mean zero log-concave real random variable $X$ one has $∥ X ∥_{p} \leq \frac{p}{q} ∥ X ∥_{q}$ for $p \geq q \geq 1$ , going beyond the well-known case of symmetri…
