This is the first course on partial differential equations in Engineering Mathematics program, Teknisk matematik, at Chalmers. Of course students who are not following this program are also welcome. The course consists of 35 lectur hourse, 14 exercise hourse and 21 hours of computer exercises and gives 4 points (5 for GU-students).

Tuesdays: weeks 2, 3, 5, 6, 7
in ** VH, ** and ** **

Thursdays: weeks 1-6 in ** EB, ** and ** **

Lectures Tuesdays 13.15-15:00 and Thursdays 10.00-11.45,

Tuesdays: Exercises 15.15-16:00, Time for questions 16.15-17.00,

The definite classroom and possible exercise groups will be announced during the first week.

**E3 Students have a separate program covering the first week
schema:**

** Monday 25/10, Tuesday 26/10, Thursday 28/10, Monday
01/11**

** Time: 17.30-19.30; Place MD6 **

This particular schema for E3 students is because of their project work during the first week. It also covers solving partial differential and integral equations using Laplace and Fourier transforms that is, partially, removed from E2's Fourier analysis course.

During the course two sets of assignments will be handed out. Each set will be divided in two parts. One part contains problems of the same type as on the final exam, but more complex and time consuming, the other part consists of computer exercises. You will account for your work by handing in the solutions to the problems and a short report on the computer work done. The home assignments can give a maximum of 12 bonus points on the final exam, where the computer exercises give 0-4 points each and the problems give 0-2 points each.

Assignment 1a
(handed in no later than week4).

Assignment 1b (handed in no later than week4).

Assignment 2a (handed in no later than week7).

Assignment 2b (handed in no later than week7).

Unfortunately, we have not been able to construct the second computer assignment in Matlab. Instead we have to use a Unix-program developed here at math called Femlab. To overcome problems using this software, Rickard will schedule with you for an extra 2 hours to demonstrate Femlab and help with problems that come up.

**The computer assignments:**

The computer assignments use Matlab as the main tool. You can sit at MC if you want to (Rickard can give you a log-in name), but as long as you have access to Matlab 5.2 you can sit anywhere. We have not booked any computer rooms or tutorial time as we don't think it will be needed. If you don't agree, tell us and we will try to arrange something.

Apart from the two bonus generating assignments, we have also made some preparatory exercises, assignment 0. They deal with interpolation (ch 5 in the book) and multidimensional calculus (ch 13). Take a look at them to see if you can learn something from them, probably you will.

Assignment 0

Assignment
1b (bonus generating)

Assignment 2b (bonus generating) (no html available, only
postscript)

Here are two examples of old exams,
(99-04-06) and
(98-12-15)

with their solutions:
solution to (99-04-06) and
solution to (98-12-15) .

The final exam is written and will contain both problems and theory questions. The grades on the exam will be:

**3:** 20-29 points

**4:** 30-39 points

**5:** 40-50 points

The ** exam will be December 14, 14.15-18.15 in VV, ** and
also ** ** no aids allowed.
The corrected exams will be available in the reception room at
Matematiskt Centrum which is open during lunch time, Monday to
Friday, no later than three weeks after the exam.

The final exam will contain a **theory question ** from the following list:

**Theorem 8.1; ** a priori error estimate for the 2
point boundary value problems,

**Theorem 8.2; ** a posteriori error estimate for the 2
point boundary value problems,

**Theorem 9.4; ** a priori error estimate for general
initial value problems,

**Theorem 21.1; ** the Lax-Milgram Theorem,

**Theorem 14.1; ** piecewise linear polynomial interpolation
in 2D,

**Theorem 15.4; ** a posteriori error estimates for the Poisson's
equation,

** Lemma 16.5; ** a discrete strong stability estimate for the heat
equation,

Students from GU **have** to do problems 2 and 24 from
**Övningsexemple i PDE1 TM**.
These should be handed in not later than at the exercise on Tuesday
week 6 (Nov. 30). This extra work is because you get 5 credit points.

An example note-book,Övningsexemple i PDE1, TM, consisting of problems from some previous exams and solutions to the Lösningar för udda uppgifter i Övningsexemple i PDE1 TM, odd problems in Övningsexemple i PDE1, are now available in the cousre homepage (ps-files) and will be distributed in second week .

There will be a **course
diary** describing the current process of
lectures/ exercises.
