Ornstein-Uhlenbeck算子的里斯变换的端点结果
Endpoint results for the Riesz transform of the Ornstein-Uhlenbeck operator
摘要:
本文引入了一个新的原子Hardy空间$X^1(γ)$,它适应于高斯测度$γ$,并证明了从$X^1(γ)$到$L^1(γ)$的与Ornstein-Uhlenbeck算子相关的一阶里斯变换的有界性.我们还提供了一个新的,简短的和几乎自包含的证明其弱型$(1,1)$。
英文摘要:
In this paper we introduce a new atomic Hardy space $X^1(γ)$ adapted to the Gauss measure $γ$, and prove the boundedness of the first order Riesz transform associated with the Ornstein-Uhlenbeck operator from $X^1(γ)$ to $L^1(γ)$. We also provide a new, short and almost self-contained proof of its weak-type $(1,1)$.
