2011 seminar talk: Maximal Cofinitary Groups

Talk held by Yi Zhang (Sun Yat-Sen University, Guangzhou, China) at the KGRC seminar on 2011-05-04.


A subgroup G in Sym(N) is called cofinitary iff every element in G but identity has finitely many fix points. In my talk, I will talk about some results and questions concerning this group.
