The Gundy-Stein decomposition with explicit constants

Mahdi Hormozi, Jie-Xiang Zhu

Let $(F_{n})_{n \geq 1}$ be a filtration and let $f \geq 0$ belong to $L^{1} (F_{\infty})$ . For the martingale $f_{n} = E [f ∣ F_{n}]$ and each $λ > 0$ we prove a G…

Hypercontractivity of Poisson Semigroups with Orthogonal Polynomial Eigenfunctions

Mahdi Hormozi, Jie-Xiang Zhu

For any $1 < p < q < \infty$ , we investigate fixed-time hypercontractive bounds from $L^{p}$ to $L^{q}$ of Poisson semigroups associated with the Ornstein--Uhlenbeck, Laguerre and Jaco…
