。我们考虑叶流形的叶状保留同胚群。我们计算余维一叶群的第一同源性。特别是,我们证明了 3 球体上的 Reeb 叶状群是完美的,而环面上的无理线性叶状群是不完美的。
. We consider the group of foliation preserving homeomorphisms of a foliated manifold. We compute the first homologies of the groups for codimension one foliations. Especially, we show that the group for the Reeb foliation on the 3-sphere is perfect and the groups for irrational linear foliations on the torus are not perfect.
