PhD Course 2009
An Introduction to Pseudospectra and their Applications
The program for the first day is as follows:
- Introduction. Presentations of participants. Formalities regarding the course.
- A slide presentation of the main points of the course. This presentation will be quite rapid, and you should think of it as a preview of things to come. Some of the items on the slides will take several hours to explain properly. The slides can be found here.
- Coffee break.
- Lecture on linear algebra. I will review a number of well known results, and present a number of new concepts. The material covered corresponds roughly to pages 2-6 in the lecture notes.
- Lecture on operator theory. I will present a number of results, which are valid in both finite dimensional and the infinite dimensional case. A the end I will get to the formal definition of the pseudospectra. I will cover most of the material on pages 11-17 in the lecture notes.
I recommend doing the exercises in the lecture notes, as we progress through the material. As of tomorrow I will include time for discussion of the exercises in the schedule.
In connection with the material presented today I recommend looking at the following exercises:
- Exercise 2.4
- Exercise 2.8
- Exercise 4.2
- Exercise 4.4
