讲座题目一：高维非线性演化方程高阶波解的构造算法及自动推导

讲座内容：主要介绍若干高维非线性演化方程高阶孤子解、周期解、有理解及不同类型高阶相互作用解的构造算法、自动交互平台构建及相关创新工作。

讲座题目二：非线性微分系统的在线计算和智能平台构建

讲座内容：A Web-based knowledge database and computing platform for nonlinear differential equations is introduced, which could provide computing and graphing based on symbolic computing system Maple and some of its built-in packages. Users can not only calculate specific types of analytical solutions of nonlinear differential systems by calling the packages, but also carry out any symbolic computations associated with equations and other kinds of simple computations in an interactive mode with visual output. The knowledge database of differential equations has all functions of the general database. Furthermore, each equation has a web page to show its properties and research results. In addition, each mathematical formula is stored in its infix form in the knowledge database and can be displayed visually.
