应兰州大学数学与统计学院李秋丽博士邀请,广东省“千百十”人才培养工程省级培养对象,广东轻工职业技术学院张赞波教授将于2017年11月27日--2017年12月1日访问数学与统计学院,期间将举办专题学术报告。
题目:Cycles and Paths in Digraphs
时间:11月28日(星期二)下午 16:30
地点:齐云楼911报告厅
摘要:Cycle problems and path problems in graphs have been studied extensively for more than half a century. They have formed a fruitful research field containing lots of interesting results and challenging problems on graph theory, algorithm design and computational complexity. In this talk, I will firstly give a rough overview on the various conditions and richful structures in this field. Then, due to my personal preference and my own research direction, I will go further into several topics on cycles and paths in digraphs, including different forms of degree conditions for hamiltonian cycles, cycles and paths of many lengths, and a special class of digraphs - tournaments.
