告人介:

   跃现为美国德克斯大学阿灵分校数学系的教授,1994年博士毕业于美国布朗大学用数学系,从国著名数学家WalterStrauss教授。刘教授是目前国上偏微分方程研究尤其是浅水波域的一流家,他的研究趣在非线性波解的适定性、定性、长时间以及数值计算等。迄今刘教授已在CPAM,ARMA, CMP, Adv. Math, J. Reine Angew. Math., JMPA, JFA, CPDE,Math.Ann., Math.Z., TAMS, SIAM-JMA, JDE等国著名刊物上90余篇。

 

告摘要:

    Inthis talk,  I start by formally deriving the simplifiedphenomenological models of

long-crestedshallow-water waves propagating in the equatorial ocean regions withthe

Corioliseffect due to the Earth's rotation. These new model equations areanalogous to

theGreen-Naghdi equations, the first-order approximations of the KdV-,BBM- or improved-Boussinesq-type, respectively. I then justifyrigorously that in the long-wave limit, unidirectional solutions of aclass of KdV- or BBM-type are well approximated by the solutions

ofthe Camassa-Holm equation with the Coriolis effect.
