Paradoxical decomposition of Group Actions and Configuration
A. Rejali, A. Yousofzadeh, M. Meisami +1
In this paper we study the notion of configuration for group actions. It is proved that some properties concerning configuration of groups can be extended for the case of group act…

Countable-configurations and paradoxical decompositions
M. Meisami, A. Rejali, A. Yousofzadeh
In this paper we define countable-configuration of groups and prove that two Hopfian groups with the same set of countable-configurations are isomorphic and vice versa. We also stu…
