奇异随机积分算子

Singular stochastic integral operators

Emiel Lorist, Mark Veraar

摘要:

本文介绍了具有算子核的奇异随机积分的Calderón-Zygmund理论。特别是,我们证明了$L^p$ -外推的结果下的核的Hörmander条件。稀疏控制和尖锐的加权边界下得到的Dini条件的内核,导致随机版本的解决方案的$A_2$ -猜想。结果被应用于获得$p$ -独立性和加权界的随机最大$L^p$ -正则性在复杂的和真正的插值尺度。从而得到了$\mathbb{R}^d$、光滑区域和角域上随机热方程的几个新的正则性结果。

英文摘要:

In this paper we introduce Calderón-Zygmund theory for singular stochastic integrals with operator-valued kernel. In particular, we prove $L^p$-extrapolation results under a Hörmander condition on the kernel. Sparse domination and sharp weighted bounds are obtained under a Dini condition on the kernel, leading to a stochastic version of the solution to the $A_2$-conjecture. The results are applied to obtain $p$-independence and weighted bounds for stochastic maximal $L^p$-regularity both in the complex and real interpolation scale. As a consequence we obtain several new regularity results for the stochastic heat equation on $\mathbb{R}^d$ and smooth and angular domains.
