地 点:北航数学与系统科学ag平台app下载学术交流厅,旧主楼321 报告摘要:In this talk, we present a numerical method and its fast implementation for the solution of a wide class of semi-linear parabolic equations including the Allen-Cahn equation as a special case. The method combines efficient decompositions of spatial difference operators on a regular mesh with stable and accurate exponential time integrators. It can deal with stiff nonlinearity and both homogeneous and inhomogeneous boundary conditions of different types. Numerical experiments demonstrate effectiveness of the new approach for both linear and nonlinear model problems. 报告人概况:鞠立力,美国南卡罗莱纳大学数学系教授,知名数值分析专家,长期从事数值分析和科学计算、CVT网格生成和图象处理等方面的研究。鞠立力教授在国际知名期刊发表学术论文40余篇,现为美国工业和应用数学学会以及美国数学会成员,从2012年起开始担任专业国际顶级期刊SIAM Journal of Numerical Analysis副主编。
