双曲群的强可达性

Strong accessibility for hyperbolic groups

Diane M. Vavrichek

摘要:

利用Delzant和Potyagailo的一个可达性结果证明了Swarup关于无2-挠Gromov双曲群的强可达性猜想。如果M是具有双曲基本群的不可约的、可定向的、紧致的3-流形,则M沿压缩圆盘和本质环交替分解的任何族都是有限的.

英文摘要:

We use an accessibility result of Delzant and Potyagailo to prove Swarup's Strong Accessibility Conjecture for Gromov hyperbolic groups with no 2-torsion. It follows that, if M is an irreducible, orientable, compact 3-manifold with hyperbolic fundamental group, then any hierarchy in which M is decomposed alternately along compressing disks and essential annuli is finite.
