Amenability of groups and semigroups characterized by Configuration
Tavakoli, Ali, Ali Rejali · arXiv (Cornell University) · 2015
In 2005, Abdollahi and Rejali, studied the relations between paradoxical decompositions and configurations for semigroups. In the present paper, we introduce another concept of amenability on semigroups and groups which includes amenability of semigroups and inner-amenability of groups. We have the previous known results to semigroups and groups satisfying this concept.
