塔斯基数为5的群

Groups with Tarski number 5

Gili Golan

摘要:

非顺从群G的塔斯基数是G的矛盾分解中的最小个数。到目前为止,已知的塔斯基数只有4和6。构造了一个Tarski数为5的群,并给出了群作用的Tarski数的一个相关结果.

英文摘要:

The Tarski number of a non-amenable group G is the minimal number of pieces in a paradoxical decomposition of G. Until now the only numbers which were known to be Tarski numbers of some groups were 4 and 6. We construct a group with Tarski number 5 and mention a related result for Tarski numbers of group actions.
