拟树上的Bushy伪特征标与群作用
Bushy pseudocharacters and group actions on quasi-trees
摘要:
给定一个群作用在一个与树拟等距的图上,我们给出了伪特征标是丛的充分条件。我们把这与M. Beststanbul和K. Fujiwara等人关于有界上同调的工作,并在伪特征标空间上得到了一些结果。
英文摘要:
Given a group acting on a graph quasi-isometric to a tree, we give sufficent conditions for a pseudocharacter to be bushy. We relate this with the conditions studied by M. Bestvina and K. Fujiwara on their work on bounded cohomology and obtain some results on the space of pseudocharacters.
