AI总结:

本文证明高阶高斯Riesz变换在原子Hardy空间到L1空间的有界性,并推广Bruno的一阶结果,适用于任意阶数和维数。

摘要:

我们将证明,与迄今为止在原子Hardy空间$\mathcal{H}^1(\mathbb R^n, γ)$上研究的高阶Riesz变换(与关于$n$维高斯测度$γ$的Ornstein-Uhlenbeck算子相关)的行为相反,新的高斯Riesz变换对于任意阶数和维数$n$,从$\mathcal{H}^1(\mathbb R^n, γ)$到$L^1(\mathbb R^n, γ)$是有界的。我们还将证明,经典的高阶高斯Riesz变换从$\mathcal{H}^1(\mathbb R^n, γ)$的一个适当子空间到$L^1(\mathbb R^n, γ)$是有界的,从而推广了Bruno关于一阶情形的结果(J. Fourier Anal. Appl. 25, 4 (2019), 1609–1631)。

英文摘要:

We will show that, contrary to the behavior of the higher order Riesz transforms studied so far on the atomic Hardy space $\mathcal{H}^1(\mathbb R^n, γ)$, associated with the Ornstein-Uhlenbeck operator with respect to the $n$-dimensional Gaussian measure $γ$, the new Gaussian Riesz transforms are bounded from $\mathcal{H}^1(\mathbb R^n, γ)$ to $L^1(\mathbb R^n, γ)$, for any order and dimension $n$. We will also prove that the classical Gaussian Riesz transforms of higher order are bounded from an adequate subspace of $\mathcal{H}^1(\mathbb R^n, γ)$ into $L^1(\mathbb R^n, γ)$, extending Bruno's result (J. Fourier Anal. Appl. 25, 4 (2019), 1609--1631) for the first order case.
