4 SWS lecture + 2 SWS problem class

Contents and Prerequisites

The aim of this lecture is to construct, analyze and discuss the efficient implementation of numerical methods for time-dependent partial differential equations (pdes). We will consider traditional methods and techniques as well as very recent research.

The students are expected to be familiar with the basics of the numerical analysis of the time integration of ordinary differential equations (Runge-Kutta and multistep methods) and of finite element methods for elliptic boundary element methods. The lecture starts with a review on Runge-Kutta and multistep methods. Some basic knowledge in functional analysis and the analysis of boundary value problem is helpful but the main results will be repeated in the lecture.

Exam

The registration for the exam is open (Number of exam 7700046, German title "Numerische Methoden für zeitabhängige partielle Differentialgleichungen", English title "Numerical Methods for Time-Dependent Partial Differential Equations"). The exams take place between August 6 and 17.

The format of the exams will be the following:

  • Until the end of the semester, we will provide you with a list of possible questions for each chapter of the lecture.
  • You randomly draw three questions from this list, each from another chapter. One question can be redrawn from the same chapter with the possibility to answer the original question.
  • Then you are given 20 minutes for preparation (without any aid). Any notes that you prepare during this time can be used in the oral exam.
  • The actual oral exam will last additional 20 minutes during which you have to answer the questions. This leaves approximatly 7 minutes for each question. If the answer is too short we expect you to present further details of the topic. In order to assure that you understand all aspects of the topic in question, you can always be asked further questions.
  • The final grade will be the mean of the grades (1-6) from the three answered questions.

The list of questions can be found here: Questions

Lecture notes (draft version)

The lecture notes provided here are a draft version, since they are written when the lecture progresses. This includes corrections shortly after the corresponding topic was discussed.

I am gratefull for any suggested corrections and improvements.

The lecture notes are a continuation of the lecture notes for the Finite Element Methods from WS 15/16.
