This site will no longer be updated (check here for news about the re-exam).

The results of the exam are now ready. They can be seen in the glass box ('Schaukasten') in front of B 409 (Siedentop). You may have a look at your exam ('Klausureinsicht') on Wednesday July 20th, at 13:00, in B 006.

15.07.2016

In the exam, you may use results from the lecture and from the homework sheets (without re-proving them) IF you tell what you use ('from lecture' is not enough) - except of course when explicitely asked to prove something.

Exercise Sheet 12 will be marked until Friday morning. You can expect to find your sheets in the return box on the first floor before noon.

Note that in Problem 4 on Exercise Sheet 11, for the original statement of the problem, it was not necessary to use the Closed Graph Theorem. However, by using the Closed Graph Theorem, it can be shown that, for the operator T to be bounded, it is not necessary to assume that the map J has closed range (see solution below). We have changed the statement of the problem accordingly. Clearly, this change does not affect the grading of your solutions.

As noted on several occasions, in the literature, the term pre-compactness is used inconsistently. Sets that in the lecture are called pre-compact are sometimes referred to as totally bounded, while pre-compact is then used interchangeably with relatively compact. In Assignment 10, Problem 2, we want you to prove whether the sets are relatively compact (not pre-compact as falsely written on the first version of the sheet).

Three minor errors on the current exercise sheet (8) have been corrected (2c(i): x non-zero, 3b: a non-zero, 4b: for all functionals f on c_0).

The re-exam (Wiederholungsklausur) will take place Wednesday, July 27th 2016 (27.07.2016), from 9:15 to 11:45.

Due to the holiday on next Monday and the lecture-free Tuesday, we encourage the students attending the tutorial class on Monday to attend one of the other classes this week and the students attending the tutorial class on Tuesday to go to one of the other classes next week (preferably not to the class on Thursday, which has 20+ students already). Marked sheets that would have been returned in one of the cancelled tutorials can be found in the return box next to the library.

The phrasing of Exercise 1c on Exercise Sheet 3 was slightly changed.

29.04.2016

An error on Exercise Sheet 2 was corrected (Problem 2d: ...is the basis for a topology...).

27.04.2016

A typo and an error on Exercise Sheet 2 was corrected (Problem 1d: super set instead of subset, Problem 2c: B is the basis for a topology, not necessarily T).

19.04.2016

Starting April 21, the lecture on Thursday will be 8.25-9.55 (and not 8.30-10.00).

12.04.2016
