每个拓扑群都是极小群的群收缩

Every topological group is a group retract of a minimal group

Michael Megrelishvili

摘要:

证明了每个Hausdorff拓扑群都是极小拓扑群的群收缩核。第一次是由佩斯托夫在1983年。我们的主要结果导致一些问题的解决方案的Arhangelskii。其中之一是关于群作为极小群的商的可表示性的问题(《拓扑学中的开放问题》第一版中的问题519)。我们的方法是基于广义海森堡群和巴拿赫空间和双线性映射的群表示所产生的群体。

英文摘要:

We show that every Hausdorff topological group is a group retract of a minimal topological group. This first was conjectured by Pestov in 1983. Our main result leads to a solution of some problems of Arhangelskii. One of them is the problem about representability of a group as a quotient of a minimal group (Problem 519 in the first edition of "Open Problems in Topology"). Our approach is based on generalized Heisenberg groups and on groups arising from group representations on Banach spaces and in bilinear mappings.
