Fibonacci型双曲群与T(5)循环表示群
Hyperbolic groups of Fibonacci type and T(5) cyclically presented groups
摘要:
建立在以前的结果有关的双曲群的Fibonacci型,我们给了一个几乎完整的分类(非初等)双曲群在这一类。我们无法精确地确定两个群的双曲性状态,即Gilbert-Howie群H(9,4),H(9,7)。我们证明了如果H(9,4)是无挠的则它不是双曲的。我们考虑T(5)循环表示群的类,并对(非初等的)双曲群进行分类,证明了Tits替代方法成立。
英文摘要:
Building on previous results concerning hyperbolicity of groups of Fibonacci type, we give an almost complete classification of the (non-elementary) hyperbolic groups within this class. We are unable to determine the hyperbolicity status of precisely two groups, namely the Gilbert-Howie groups H(9,4), H(9,7). We show that if H(9,4) is torsion-free then it is not hyperbolic. We consider the class of T(5) cyclically presented groups and classify the (non-elementary) hyperbolic groups and show that the Tits alternative holds.
