应数学系邀请,加拿大麦吉尔大学梅茗教授将于7月19日访问数学系并作报告。 报告题目:Asymptotic behavior of solutions to reaction-diffusion equations with time-delay 报告时间:7月20日上午9:00-10:30 报告地点:格物楼503 报告摘要:In this talk, we consider a mono-stable reaction-diffusion equation with time-delay, which represents the population model of single species like Australian blowflies. When the system of equations is non-monotone, it possesses some monotone or non-monotone traveling waves dependent on the time-delay to be small or big. We clarify that, for a certain given initial data, the corresponding solution will converge to a certain monotone or non-monotone traveling wave, where the wave speed can be specified due to how fast the initial data vanishes at far field x=?∞, the location of the wave can be also determined by the given initial data, and the shape of the wave is determined by the size of the time-delay. 报告人简介:梅茗,加拿大McGill大学Adjunct Professor及Champlain公司的终身教授。1996年博士毕业于日本国立金泽大学, 1996-1998年在日本金泽大学从事文部省JSPS博士后研究。1999年为金泽大学讲师。2000-2002在奥地利维也纳理工大学及加拿大Alberta大学和McGill大学从事博士后研究,2002-2005任加拿大Concordia大学LTA助理教授及研究副教授。2005至今为加拿大Champlain公司的终身教授及McGill大学Adjunct Professor。梅茗教授是偏微分方程领域知名学者,主要从事流体力学中半导体偏微分方程和生物数学中带时滞反应扩散方程研究,在Archive Rational Math.
