NDEmathema: An Innovative Web-based Automated Symbolic Computing Platform for Nonlinear Differential Equations. In this talk, a Web-based automated symbolic computing platform for nonlinear differential equations called NDEmathema is introduced, which provides computing and graphing based on Maple and some Maple packages. In this online platform, users not only can calculate specific types of analytical solutions of nonlinear differential systems by calling the built-in software packages, but also can carry out any symbolic computations associated with equations and other kinds of simple symbolic computations in the interactive mode with visual output.
