To day I did the two examples on page 91.
During the exercise section I did problem 17 on page 70.
Next monday I 'll speek about theorem 3.11 (without proof)
and continue with chapter 3.
I'll tone down the proves, and concentrate on the content of the results and examples.
Next wednesday we continue with exercises from "exercises 4".
New exercises from chapter 3 will come soon.
