June 23, 2003. Yi Zhang (Sun Yat-Sen University, P.R.China; and University of Michigan, Ann Arbor, MI, USA). Maximal Cofinitary Groups

A permutation on N is cofinitary iff it has only finitely many fixed points. A permutation group G is cofinitary iff every element in G but identity is a cofinitary permutation. In my talk, I am going to discuss the possible cardinalities of maximal cofinitary permutation groups.
