TITLE	On the Study of Phylogenetic Networks
ABSTRACT	Phylogenetic networks have replaced phylogenetic trees in many applications in biology whitin past few decades. Biologists are particularly interested in some classes of phylogenetic networks. In this talk, I will present our (with M. Fuchs and L. Zhang) recent work of counting the major classes of phylogenetic networks which are believed to be of great help to the study of phylogenetics. Moreover, I will also outline some open problems which we plan to handle in the near future.
