702732 Einführung in die höhere numerische Mathematik: Numerik partieller Differentialgleichungen
Wintersemester 2015/2016 | Stand: 11.01.2016 | LV auf Merkliste setzenAbsolventinnen und Absolventen dieses Moduls haben einen Überblick über einige aktuelle Fragestellungen der höheren numerischen Mathematik und die Methoden zu deren Behandlung erworben. Weiters haben sie ein vertieftes Verständnis für das Gebiet der numerischen Mathematik erlangt und sind in der Lage, typische Probleme dieses Fachgebietes zu analysieren und zu lösen.
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.
