讲座题目:  Existence of Traveling Waves of Auto-Catalytic Systems with Decay

讲座时间:  2016年6月7日 下午3:00-5:00

讲座地点:  理学院9层学术报告厅 (914)

主讲人:  齐远伟 教授

内容摘要:  
 In this talk I shall present most recent works  on the existence of traveling waves of a class of reaction-diffusion systems which model the pre-mixed isothermal autocatalytic chemical reaction of order m ( m>1) between two chemical species, a reactant and an auto-catalyst, and a linear decay. Our result shows that the set of speed is contained in a bounded interval. This is in strong contrast to the reaction-diffusion systems of autocatalytic chemical reaction of the same order without decay, which was shown by various authors that the set of traveling wave speeds contains [c*, ∞) for some c* > 0.
主讲简介:  
齐远伟,University of Central Florida  教授。他1982年毕业于北京大学数学系,1985年在中科院获得硕士学位,1990年在牛津大学取得博士学位,曾先后在香港科技大学、UC Santa Barbarra任教;也曾在山西大学担任山西省百人计划教授。齐教授是国际上有一定影响的偏微分方程方向的专家,自1994年以来曾多次在牛津大学、British Columbia 大学、中国科学院、清华大学等学校和科研单位进行学术交流;自1998年以来先后二十多次被邀请在世界学术会议上做邀请报告。

In this talk I shall present most recent works  on the existence of traveling waves of a class of reaction-diffusion systems which model the pre-mixed isothermal autocatalytic chemical reaction of order m ( m>1) between two chemical species, a reactant and an auto-catalyst, and a linear decay. Our result shows that the set of speed is contained in a bounded interval. This is in strong contrast to the reaction-diffusion systems of autocatalytic chemical reaction of the same order without decay, which was shown by various authors that the set of traveling wave speeds contains [c*∞) for some c* > 0.
