与Ornstein-Uhlenbeck算子相关的一阶里斯变换的端点估计

Endpoint estimates for first-order Riesz transforms associated to the Ornstein-Uhlenbeck operator

G. Mauceri, S. Meda, P. Sjögren

摘要:

在具有Gauss测度g的欧几里得空间中,考虑了Ornstein-Uhlenbeck半群的无穷小生成元所对应的所有一阶里斯变换.已知这些算子在L^p(g)上有界,其中1<p< \infty。我们确定它们中的哪些是从H^1(g)到L^1(g)和从L^ \infty(g)到BMO(g)有界的。这里H^1(g)和BMO(g)是前两位作者在此背景下引入的空间。令人惊讶的是,我们发现,结果取决于周围空间的尺寸。

英文摘要:

In the setting of Euclidean space with the Gaussian measure g, we consider all first-order Riesz transforms associated to the infinitesimal generator of the Ornstein-Uhlenbeck semigroup. These operators are known to be bounded on L^p(g), for 1<p<\infty. We determine which of them are bounded from H^1(g) to L^1(g) and from L^\infty(g) to BMO(g). Here H^1(g) and BMO(g) are the spaces introduced in this setting by the first two authors. Surprisingly, we find that the results depend on the dimension of the ambient space.
