Co-Hopf虚自由群与初等等价

Co-Hopfian virtually free groups and elementary equivalence

Simon André

摘要:

证明了两个余Hopfian群生成的虚自由群初等等价当且仅当它们同构。我们还证明了在模型论的意义下,余霍普夫群生成的虚自由群是齐次的.

英文摘要:

We prove that two co-Hopfian finitely generated virtually free groups are elementarily equivalent if and only if they are isomorphic. We also prove that co-Hopfian finitely generated virtually free groups are homogeneous in the sense of model theory.
