李群上的Besov和Triebel-Lizorkin空间

Besov and Triebel--Lizorkin spaces on Lie groups

Tommaso Bruno, Marco M. Peloso, Maria Vallarino

摘要:

本文发展了具有次黎曼结构的一般非紧李群上的Besov和Triebel-Lizorkin空间理论。这样的空间被定义的亚椭圆次拉普拉斯算子与漂移,并赋予一个措施,其密度相对于右哈尔措施是一个连续的积极特征的群体。我们证明了它们的范数的几个等价刻画,建立了与最近引进的索伯列夫空间的比较结果,并研究了它们的复插值和代数性质.

英文摘要:

In this paper we develop a theory of Besov and Triebel--Lizorkin spaces on general noncompact Lie groups endowed with a sub-Riemannian structure. Such spaces are defined by means of hypoelliptic sub-Laplacians with drift, and endowed with a measure whose density with respect to a right Haar measure is a continuous positive character of the group. We prove several equivalent characterizations of their norms, we establish comparison results also involving Sobolev spaces of recent introduction, and investigate their complex interpolation and algebra properties.
