算子半群的帐篷空间

Tent Spaces Associated with Semigroups of Operators

Tao Mei

摘要:

研究了一般测度空间$(Ω, μ)$上的帐篷空间.我们假设在$L^p(Ω, μ)$上存在一个正算子半群满足单调性,但不假设$Ω$上有任何几何/度量结构.半群在欧几里得空间中起着与锥和立方体上的积分相同的作用。然后研究了一般测度空间上的BMO空间,得到了February man的$H^1$ -BMO对偶理论的一个类似.在不假设单调性的情况下,得到了一个$H^1$ -BMO对偶不等式.所有的结果证明在一个更一般的设置,即非交换$L^p$空间。

英文摘要:

We study tent spaces on general measure spaces $(Ω, μ)$. We assume that there exists a semigroup of positive operators on $L^p(Ω, μ)$ satisfying a monotone property but do not assume any geometric/metric structure on $Ω$. The semigroup plays the same role as integrals on cones and cubes in Euclidean spaces. We then study BMO spaces on general measure spaces and get an analogue of Fefferman's $H^1$-BMO duality theory. We also get a $H^1$-BMO duality inequality without assuming the monotone property. All the results are proved in a more general setting, namely for noncommutative $L^p$ spaces.
