摘要:

本文考虑Banach值函数在逆高斯背景下由算子$\mathcal{A}=-\fracΔ{2}-x\nabla$所对应的半群所定义的Littlewood-Paley函数.利用$\mathcal{A}$ -Littlewood-Paley函数的$L^p(\mathbb{R}^n,γ_{-1})$ -性质刻画了一致凸光滑的巴拿赫空间.我们还利用与$\mathcal{A}$相关的Littlewood-Paley函数刻画了具有UMD性质的Köthe函数空间.

英文摘要:

In this paper we consider Littlewood-Paley functions defined by the semigroups associated with the operator $\mathcal{A}=-\fracΔ{2}-x\nabla$ in the inverse Gaussian setting for Banach valued functions. We characterize the uniformly convex and smooth Banach spaces by using $L^p(\mathbb{R}^n,γ_{-1})$- properties of the $\mathcal{A}$-Littlewood-Paley functions. We also use Littlewood-Paley functions associated with $\mathcal{A}$ to characterize the Köthe function spaces with the UMD property.
