Weekly hours

4 SWS lecture + 2 SWS problem class

Contents and Prerequisites

This lecture provides an introduction to the theory of finite element methods for elliptic boundary value problems in dimension one and two. In particular, stability and convergence will be proved and concepts for the implementation of such methods will be explained. Moreover, the numerical solution of elliptic eigenvalue problems and mixed methods for saddle point problems will be investigated.

The students are expected to be familiar with the basics of numerical analysis, in particular interpolation, numerical integration, solution of linear systems and eigenvalue problems. 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.

We offer two dates for the oral examinations which are February 17 and March 31.

The registration for the oral examinations is now open under https://campus.studium.kit.edu/english/exams/registration.php. Registration is open until February 10 / March 24 and you can resign until February 14 / March 28.

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 Chapter 1-5

Schedule for the exams on Wednesday, February 17.
Schedule for the exams on Thursday March 31 and Friday April 1.

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.

Supplementary material

The german lecture notes include the chapters from previous lectures and will also be updated as the lecture progresses. There maybe slight differences between the english and the german version.
