有限von Neumann Algebras中酉群的李群-李代数对应

Lie Group-Lie Algebra Correspondences of Unitary Groups in Finite von Neumann Algebras

Hiroshi Ando, Yasumichi Matsuzawa

摘要:

本文对具有强算子拓扑的$U(\mathcal{H})$的Hilbert空间$\mathcal{H}$中酉群$U(\mathcal{H})$的适当闭子群是否存在李代数的问题给出了肯定的回答.更精确地说,对于有限von Neumann代数$\mathfrak{M}$中酉群$U(\mathfrak{M})$的任何强闭子群$G$,我们证明了$G$的强连续单参数子群的所有生成元的集合关于强预解式拓扑构成完备拓扑李代数.我们还从张量范畴的角度刻画了所有隶属于$\mathfrak{M}$的稠密闭算子的代数$\mathfrak{M}$.

英文摘要:

We give an affirmative answer to the question whether there exist Lie algebras for suitable closed subgroups of the unitary group $U(\mathcal{H})$ in a Hilbert space $\mathcal{H}$ with $U(\mathcal{H})$ equipped with the strong operator topology. More precisely, for any strongly closed subgroup $G$ of the unitary group $U(\mathfrak{M})$ in a finite von Neumann algebra $\mathfrak{M}$, we show that the set of all generators of strongly continuous one-parameter subgroups of $G$ forms a complete topological Lie algebra with respect to the strong resolvent topology. We also characterize the algebra $\mathfrak{M}$ of all densely defined closed operators affiliated with $\mathfrak{M}$ from the viewpoint of a tensor category.
