sofic 群与自由群上的 profinite 拓扑

摘要
我们给出了弱 sofic 群(w-sofic groups)的定义。我们的定义是 sofic 群定义的自然推广,其中我们用有限群上的一般双不变度量代替了对称群上的 Hamming 度量。非 w-sofic 群的存在性等价于关于自由群上 profinite 拓扑的某个猜想。

5 pages, 1 figure. We extend the exposition. We hope it is better now. In greate part it is due to anonimous referee work. The results are the same as in previous version
