带一致有界上循环的拟不变态

Quasi-invariant states with uniformly bounded cocycles

Ameur Dhahri, Eric Ricard

AI总结:

该研究从分析角度探究拟不变态概念,刻画了带一致有界上循环的拟不变态的结构,并借此应用经典定理得到不动点条件期望与额外假设下的不变半有限迹,丰富了算子代数相关理论。

摘要:

我们从分析视角研究了文献[2,3]中提出的拟不变态概念,给出了带一致有界上循环的拟不变态的结构。作为推论,我们可应用Kovacs和Szucs的定理得到不动点上的条件期望,还可在额外假设下应用Stormer的定理得到不变的半有限迹。

英文摘要:

We investigate the notion of quasi-invariant states introduced in [2, 3] from an analytic viewpoint.We give the structures of quasi-invariant states with uniformly bounded cocycles. As a consequence, we can apply a Theorem of Kovacs and Szucs to get a conditional expectation on fixed points and another of Stormer to get an invariant semifinite trace under extra assumptions.
