双曲群的正规子群的共轭性

Conjugacy in normal subgroups of hyperbolic groups

Armando Martino, Ashot Minasyan

摘要:

设N是Gromov双曲群G的一个N-生成正规子群.根据G/N的相应性质,建立了N有可解共轭问题和共轭可分的判据。证明了F. Haglund's和D.怀斯版本的里普斯构造是遗传共轭可分的。然后,我们使用这种结构产生的第一个例子,生成和提出的共轭可分群,包含非(共轭可分)子群的有限指数。

英文摘要:

Let N be a finitely generated normal subgroup of a Gromov hyperbolic group G. We establish criteria for N to have solvable conjugacy problem and be conjugacy separable in terms of the corresponding properties of G/N. We show that the hyperbolic group from F. Haglund's and D. Wise's version of Rips's construction is hereditarily conjugacy separable. We then use this construction to produce first examples of finitely generated and finitely presented conjugacy separable groups that contain non-(conjugacy separable) subgroups of finite index.
