SF3625 HT18-1 Partial Differential Equations
SF3625 HT18-1 Partial Differential Equations
The Final lecture will be on Friday the 14th in F11 at 8:15. (sorry about the time, but it was the only I could find)
Second set of homework (due 7th December) can be found here: Homework_2_SF3625-2.pdf
First set of Homework can be found here: Homework_1_SF3625.pdf. It is due on the 18th of October (before midnight).
Examination: The role of the examination will be to make sure that you read through the course book once and thinks through the material. There will be three sets of homework during the course, these are mandatory and will be marked pass/fail.
The final exam will consist of 4 problems. Two of these problems will be taken from your homework sets (or slight variations of homework problems). This means that you will benefit from solving the more difficult homework problems (since you will get those marked). The final exam is also pass/fail and the idea is that everyone that tries hard and reads the book will pass - however no one will pass without knowing some basic PDE theory.
Time: Thursdays 13:15-15:00 from September 6th to December 20th (except October 25th).
Place: Room 3418 in the mathematics department.
Course book: Lawrence C. Evans "Partial Differential Equations".
Brief course description: We will cover the basics of the theory of partial differential equations (PDE) at graduate level. The course will more or less be split into five parts. The first part will cover potential theory methods (Newtonian kernels, Green's functions et.c) for the three big constant coefficient partial differential equations: the Laplace, heat and wave equations. These equations are also covered in most masters courses in PDE - so you may view them as repetition or you may feel confident that you can follow this course even if you haven't studied PDE at masters level.
In the second part of the course we will cover the fundamentals of Sobolev spaces. Sobolev spaces are spaces of functions that have derivatives in an appropriate weak sense which makes them ideal for applying functional analytic methods to study PDE.
In the third and fourth part of the course we will use Sobolev spaces to study more general elliptic and evolution equations.
The final part of the course will be a brief introduction to the calculus of variations.

The course contains rather much material and we will therefore not be able to cover all pages during the lectures. I will try to give more detailed reading instructions during the term (which parts that can be skimmed over and which parts you must read carefully).
Examination: We will have approximately three homework assignments during term and the course will end with a written exam (probably in January).
