圈积上的不变状态

Invariant states on the wreath product

A. V. Dudko, N. I. Nessonov

摘要:

设$\mathfrak{S}_\infty$是无穷置换群,$Γ$是可分拓扑群.圈积$Γ\wr \mathfrak{S}_\infty$是$\mathfrak{S}_\infty$在$Γ^\infty_e=\{[γ_i]_{i=1}^\infty : γ_i\in Γ,\textit{only finitely many}γ_i\neq e\}$上的通常置换作用的半直积$Γ^\infty_e \rtimes \mathfrak{S}_\infty$。本文给出了满足条件φ(sgs^{-1})= φ(g)\text{for each} g \in <$\wr \mathfrak{S}_\ infty,s \in \mathfrak{S}_\ infty的群$Γ\wr\mathfrak{S}_\infty,$上不可分解态$φ$的完整描述。

英文摘要:

Let $\mathfrak{S}_\infty$ be the infinity permutation group and $Γ$ be a separable topological group. The wreath product $Γ\wr \mathfrak{S}_\infty$ is the semidirect product $Γ^\infty_e \rtimes \mathfrak{S}_\infty$ for the usual permutation action of $\mathfrak{S}_\infty$ on $Γ^\infty_e=\{[γ_i]_{i=1}^\infty : γ_i\in Γ,\textit{only finitely many}γ_i\neq e\}$. In this paper we obtain the full description of indecomposable states $φ$ on the group $Γ\wr\mathfrak{S}_\infty,$ satisfying the condition: φ(sgs^{-1})= φ(g)\text{for each}g\in Γ\wr \mathfrak{S}_\infty,s\in\mathfrak{S}_\infty.
