关于三维拓扑环的乘法群

On the multiplication groups of three-dimensional topological loops

Ágota Figula

摘要:

阐明了$3$维单连通拓扑环的乘法群即幂零李群的结构,证明了极小作用在$3$维流形上的不可解李群不能成为$3$维拓扑环的乘法群.在任何丝状群${\mathcal F}_{n+2}$和${\mathcal F}_{m+2}$与$n, m > 1$的幂零李群中,直积${\mathcal F}_{n+2} \times \mathbb R$和直积${\mathcal F}_{n+2} \times _Z {\mathcal F}_{m+2}$与合并中心$Z$作为$3$维拓扑环的乘法群出现。为了得到这个结果,我们将所有具有$4$维幂零李群的$3$维单连通拓扑环分类为由左平移拓扑生成的群.

英文摘要:

We clarify the structure of nilpotent Lie groups which are multiplication groups of $3$-dimensional simply connected topological loops and prove that non-solvable Lie groups acting minimally on $3$-dimensional manifolds cannot be the multiplication group of $3$-dimensional topological loops. Among the nilpotent Lie groups for any filiform groups ${\mathcal F}_{n+2}$ and ${\mathcal F}_{m+2}$ with $n, m > 1$, the direct product ${\mathcal F}_{n+2} \times \mathbb R$ and the direct product ${\mathcal F}_{n+2} \times _Z {\mathcal F}_{m+2}$ with amalgamated center $Z$ occur as the multiplication group of $3$-dimensional topological loops. To obtain this result we classify all $3$-dimensional simply connected topological loops having a $4$-dimensional nilpotent Lie group as the group topologically generated by the left translations.
