摘要受超有限等价关系研究的启发,我们定义了可数群的一个染色性质。我们证明了每个可数群都有染色性质。这意味着G在2G上的移位作用的自由部分的闭完全截面的紧性定理。我们的定理推广了关于的已知结果。
Abstract Motivated by research on hyperfinite equivalence relations we define a coloring property for countable groups. We prove that every countable group has the coloring property. This implies a compactness theorem for closed complete sections of the free part of the shift action of G on 2G. Our theorems generalize known results about .
