周五公众报告

 

报告题目:Stability of circulant graphs

 

报告人: Binzhou Xia (The University of Melbourne)

 

时间地点:914日下午4:00-5:00 后主楼1124

 

邀请人:吕本建

 

报告摘要: A graph is said to be stable if its canonical double cover has no unexpected symmetries.Graph stability has been studied extensively in the literature from different viewpoints. In this talk I'll first review these viewpoints and then focus on the stability of circulant graphs.In particular, I'll give an answer to a question of Wilson in 2008 on the stability of arc-transitive circulant graphs and infinitely many counterexamples to a conjecture of Marusic, Scapellato and Zagaglia Salvi in 1989.

 

 

周五学院公众报告主旨:讲解现代数学中的基本概念、重要结果及其数学思想的起源、方法的创新等,扩展我们的教师和研究生的视野、提高数学修养以及增强学院的学术氛围。邀请各方向的专家用通俗易懂的报告内容、自由互动的讲解方式展现现代数学中重要的基本概念和深刻原理,让听众可以领略到现代数学理论其实是来源于一些大学或研究生阶段就熟知的古典数学中的想法和结论。希望这些报告有助于高年级的本科生、研究生和教师更全面的认识现代数学、享受数学之美。欢迎大家踊跃参与!
