题目：The Joint Tree Model For Graph Embedding.
时间： 4月17日 早上10:00-10:50
摘要：The basic idea of this model is to transfer the rotation system in Heffter-Edmonds's embedding model to a cyclically ordered string of letters. The joint tree model is very helpful when we study the graph embedding problems, such as minimum genus of a graph, genus distribution of a graph etc.
