702732 Introduction to Higher Numerical Mathematics: Numerical methods for partial differential equations
winter semester 2015/2016 | Last update: 11.01.2016 | Place course on memo listGraduates of this module have an overview of some current issues in higher numerical analysis and acquired the methods for their treatment. Furthermore, they gained deeper understanding of the field of numerical analysis and are able to study and solve problems of this field.
In this lecture we will introduce a number of partial differential equations (PDEs) that are important in applications. Based on these equations numerical methods are introduced, explained, and analyzed which enable the efficient numerical solution of the PDE under consideration. We consider methods for both space and time discretization. Special emphasize is devoted to the the selection of a suitable numerical method for a given class of PDEs. A more detailed outline of the lecture and the methods covered can be found below.
