General Information

Description

The mathematical description of many physical phenomena naturally leads to nonlinear partial differential equations. While, in some cases, these are commonly approximated by linear equations (e.g., heat flow), this is often not possible, because the structure of the problem if far from being linear.

In this lecture we will consider various aspects of nonlinear partial differential equations. On the one hand we will discuss mathematical modelling and analytical questions. On the other hand we will introduce basic numerical methods for such problems, ranging from discretization to efficient iterative methods.

The problems considered will, e.g., cover applications form material science (phase field models), and bio-mechanics.

Target Audience

Advanced students in the Master Program Mathematics and of BMS. Various possible topics for a Master thesis will come up during this course.

Prerequisites

Basic knowledge on partial differential equations and their numerical solution (e.g. Numerics III).

Registration

All participants should register at the KVV, so that we know who is participating. The overall number of participants is also necessary to justify the equipment of the course. In addition, depending on your program of study, you have to register in the Campus Management.

Exercises and Criteria for a Certificate

Tutorial & Exercises

• The tutorial offers the possibility to discuss and better understand the presented material and exercises. Furthermore solutions of exercises are presented by the students.
• Each week a sheet with exercises will be made available electronically on this web page (see below).
• The exercises are intended to be solved by teams of two.
• The exercises consist of theoretical and numerical problems that should be solved by the teams.
• Programming exercises should be solved using Matlab (available at the students computer pool at the institute). Both types of exercises are rated separately.
• The solutions have to be handed in before the tutorial.
• The solutions of the numerical problems should be delivered by email to tobias.kies@fu-berlin.de. Note that a complete solution for a numerical experiment consists of a running Matlab code, a program executing the required test runs, and protocols of the execution of these test runs. Delivering a correct and running code without knowing what is going on in the code will be regarded and rated as attempt of deception.

Exam

• The exam will take place on Thursday, the 16th of February, from 14h-16h in the room SR 007/008 in Arnimallee 6.
• The test will be in written form and take 90 minutes. We ask you to already be there at 14:00.
• Please bring the following: an id card with your picture on it (passport, Personalausweis or drivers license are okay but your student id is not enough), a pen to write with (no pencil, no red pens) and some paper to write on.
• Optionally you may also bring any notes you have (it does not matter whether they are handwritten or not) and any books you may find helpful. You can also bring a non-programmable calculator (although we will make sure that you can solve the questions also without one). Please note that you may not share any of the documents/books/devices that you have brought with others.

Criteria for the Certificate

Necessary and sufficient for a certificate are:

• exam: passing the exam
• tutorial score: at least 60% points in theoretical as well as programming exercises
• participation: 85% attendence in the tutorial (not checked)

Certificates are graded according to the result of the exam.
