应数学系杨畅博士和哈工大国际合作处邀请,法国马赛大学Michel Mehrenberger教授于2019113日至119日访问哈工大数学系。Mehrenberger教授的研究方向包括Vlasov方程的数值求解方法,半拉格郎日方法,等离子体物理的数值模拟,多尺度问题的数值求解等。他参与核聚变ITER项目在欧洲的研究课题,该项目将为人类解决未来能源危机找到新的希望。

本次到访哈工大数学系,Mehrenberger教授将带来针对二阶线性化Vlasov-Poisson方程的渐近性质做系列讲座。

讲座的时间地点如下:

2019114900-1030,格物楼503,《Asymptotic behavior of second order linearized Vlasov-Poisson equations near an homogeneous equilibrium I: derivation of the dispersion relations and first order expansion

20191141030-1200,格物楼503,《Asymptotic  behavior of second order linearized Vlasov-Poisson equations near an homogeneous equilibrium II: resolution and expansion of the second order equation

20191141400-1530,格物楼503,《Asymptotic  behavior of second order linearized Vlasov-Poisson equations near an homogeneous equilibrium III: numerical results

系列讲座的摘要如下:

In this short course, we consider the Vlasov-Poisson equations and its numerical approximation. In order to check the validity of the numerical solution a common tool is to study the dispersion relation which consists in comparing the solution with a «formula » coming from the the study of the first order linearized Vlasov-Poisson equation. We focus here on the extension of this methodology to the second order case. This a joint work with Joackim Bernier (University of Rennes, France).
