局部紧半群生成的量子半群

Quantum semigroups generated by locally compact semigroups

Marat A. Aukhadiev, Yulia N. Kuznetsova

摘要:

设$S$是第二可数局部紧群$G$的子半群,使得$S^{-1}S=G$ .考虑由$L^2(S)$中$S$的所有元素平移算子生成的$C^*$ -代数$C^*_δ(S)$.我们证明了这个代数允许一个余乘,这使它成为一个紧凑的量子半群。对于由$C^*_δ(S)$生成的冯诺依曼代数$VN(S)$也证明了同样的结果。

英文摘要:

Let $S$ be a subsemigroup of a second countable locally compact group $G$, such that $S^{-1}S=G$. We consider the $C^*$-algebra $C^*_δ(S)$ generated by the operators of translation by all elements of $S$ in $L^2(S)$. We show that this algebra admits a comultiplication which turns it into a compact quantum semigroup. The same is proved for the von Neumann algebra $VN(S)$ generated by $C^*_δ(S)$.
