一类混合积的Magnus定理

A Magnus theorem for some amalgamated products

Carsten Feldkamp

摘要:

一个群$G$具有Magnus性质,如果对于每两个具有相同正规闭包的元素$u,v \in G$,$u$在$G$中共轭到$v$或$v^{-1}$。本文证明了亏格为3的闭非可定向曲面的基本群的某些合并积的Magnus性质。这回答了O. Bogopolski和K. Sviridov等人对亏格$g > 3$得到了类似的结果。

英文摘要:

A group $G$ possesses the Magnus property if for every two elements $u,v \in G$ with the same normal closure, $u$ is conjugate in $G$ to $v$ or $v^{-1}$. We prove the Magnus property for some amalgamated products including the fundamental group of a closed non-orientable surface of genus 3. This answers a question of O. Bogopolski and K. Sviridov, who obtained the analogous result for genus $g > 3$.
