## Problem Sheet 13 (for January 31)

### Comments to the exercise sheets:

1. Sheet 4, exercise 3 (d): A condition on f is needed (corrected).
2. Sheet 5, exercise 4: $\R^d$ should be replaced by $[0,1]^d$ (corrected).
3. Sheet 5: Since there was not enough time to discuss Exercises 2 and 3, I have uploaded the solution to sheet 5. There are also some additional remarks concerning exercise 4.$4. Sheet 6: Since there was not enough time to discuss Exercise 2, I have uploaded the solution. 5. Sheet 7, exercise 3:$|x|\to 0$should be replaced by$|x|\to \infty$(corrected). 6. Sheet 7: Since there was not enough time to discuss Exercises 4, I have uploaded the solution. See also the footnote in exercise 1 concerning a question raised in class. 7. I have uploaded the solution to sheet 8. 8. Sheet 12, exercise 1: Typo corrected (the order of$A$and$K$is reversed). Exercise 2: Added definition of$W_+$,$W_-\$.
