Lecture:
Tuesdays 10:20 - 12:00, R510 (with a 10-minute break)
Practice:
Tuesdays 14:15 - 15:45, R510
Material: The lecture does not follow any (English) book, but different topics can be found in the following books:
Lawrence C. Evans, Partial Differential Equations, AMS, Providence, 2002.
Haim Brezis, Functional Analysis, Sobolev Spaces and Partial Differential Equations, Springer, 2010.
Vladimir Arnold, Lectures on Partial Differential Equations, Springer, 2004.
Exercises can be found at the end of each above-mentioned book.
Requirements:
1. For the practice part:
During the semester, there are going to be two midterms.
There are also some bonus problems at the end of each practice part, which can be solved at home and then submitted on the next practice session.
Grades at the end of the semester: (the points are subject to modification, but only downwards)
40-59: grade 2
60-79: grade 3
80-99: grade 4
above 100: grade 5
2. For the lecture part:
The course ends with a written exam.
It has two parts: the first part consists of small questions, like stating a theorem, or some easy questions which will be answered during the semester as "remarks" (or they are trivial consequences of some theorems).
In the second part you have to describe a part of the material thoroughly, but you will be guided by some helping questions.
