If it is _completely_ impossible for you to come Mon/Tue you may come to the secretary (in B-411) _after_ October 24th.

Note: The bonus for the homework was counted also for the Make-up exam / Wiederholungsklausur.

Make-up exam / Wiederholungsklausur:

Time and place: Saturday 20. October 2012, 09:00-11:00 (in B 052 and ??).

Material and conditions: As for the Exam/Klausur on July 16th (see below).

If you wish to participate, sign up on the `Lecture Assistant' (under `Funktionalanalysis (Wiederholungsklausuranmeldung) (Soerensen)', group `WI-KlausurOkt20') before Wednesday Aug 29 12:00 (noon) Monday Oct 1st 12:00 (noon) (EXTENDED!). Please fill in everything including email address.)

NOTE: Change of rules of participation!:

EVERYONE who participated in the Exam/Klausur (on July 16th) (_and_ signed up as described above) may participate in the Make-up exam/Wiederholungsklausur (even _if_ they passed the Exam on July 16th).
(Jeder, der/die an dem Klausur am 16 Juli teilgenommen hat, darf, nach Anmeldung, am Wiederholungsklausur am 20 Okt teilnehmen.)

If you _failed_ the exam on July 16th, you may participate in the mark-up exam/Wiederholungsklausur on Oct 20th (if and only if you sign up as described above).

If you _passed_ the exam on July 16th, and do NOT sign up as described above (at the latest by August 29th), your mark (`Note') from July 16th will be reported to the Pruefungsamt (on Aug 29th). After this, the mark _cannot_ be changed. - After this, you may pick up your Schein at the secretary (in B-411).

If you _passed_ the exam on July 16th, and _do_ participate in the Make-up exam/Wiederholungsklausur, your final mark will be the best of the two marks, from July 16th and that of Oct 20th.

Preparation (suggestions):

Read and understand your lecture notes.

Go through the Exercises and Problems from class again (their solutions are online until the mark-up exam/Wiederholungsklausur Oct. 20th).
Don't only do the details, also try to understand, in each exercise, what was the main idea that did the trick.

Some extra, exam-relevant, exercises to practise on (zum ueben) are here (solutions will _not_ be given). Also, there will be one or more extra exercise sessions (on _some_ of these exercises, plus questions) in October (see above).

(For all questions, please email Prof. Sørensen - subject `Functional Analysis'.)

General information for the course:

Functional analysis can be viewed as ``linear algebra on infinite-dimensional vector spaces'', where these spaces (often) are sets of functions. As such it is a merger of analysis and linear algebra. The concepts and results of functional analysis are important to a number of other mathematical disciplines, e.g., numerical mathematics, approximation theory, partial differential equations, and also to stochastics; not to mention that the mathematical foundations of quantum physics rely entirely on functional analysis. This course will present the standard introductory material to functional analysis (Banach and Hilbert spaces, dual spaces, Hahn-Banach Thm., Baire Thm., Open Mapping Thm., Closed Graph Thm.). We will also cover Fredholm theory for compact operators and the spectral theorem. These are powerful tools for applications to PDE's and quantum mechanics, respectively.

Students of Mathematics, Wirtschaftsmathematik, and physics; students in the International Master Programme.
("Gilt für Bachelorprüfungen Mathematik (WP4) und Wirtschaftsmathematik (P12), Masterprüfung Wirtschaftsmathematik (WP11), Diplomhauptprüfung Mathematik (RM,AM), Diplomhauptprüfung Wirtschaftsmathematik (Kernfach D)").

Introductory courses in analysis and linear algebra (Analysis I-III, Lineare Algebra I-II).

Requirement for passing the course:
The course ends with a written final exam (time: to be announced; more details later). The final grade is given based upon the performance on this exam. It is expected that 50% performance will be enough to pass the course, but this number may change slightly. There will be weekly exercise sheets that can be handed in for grading (in the designated box near the library on the first floor). NO LATE HOMEWORK IS ACCEPTED. (For more details, see the Exercise webpage.) To encourage the regular course work during the semester, the correct solutions to the homework will be counted as bonus points towards the final grade as follows: If one gets 40% or more of the total points on the Exercise Sheets, then the final mark at the Klausur is raised by 0.3/0.4 EXCEPT for marks below 4.0 (and, for 1.0 of course!)

Endklausur (Final (written) Exam):

Time: Monday 16 July 18:30-20:30
Place: Room B-052

Material: Complete material of all lectures up until and including Wednesday July 11th, and Exercise sheets up until and including Sheet 12.

You are allowed to bring 1 (one) two-sided HANDWRITTEN cheat sheet (Spickzettel): a piece of A4-paper on which you have written (on both sides) whatever you think might be useful for the Klausur/exam. Anyone with a (partially or entirely) printed/photo copied cheat sheet will be expelled from the exam. You may not bring anything else (apart from pens/pencils), i.e., no books, notes from class, homework, solutions to homework etc. Examination booklet and extra paper will be provided. Put your name on every sheet you wish to hand in, and write readable.

The final grade is determined by the final exam plus the bonus points from homework, see the precise rules above.

There will be no make-up exam (keine Nachholklausur). If necessary, there will be another exam (Wiederholungsklausur) offered later for those who failed the first one (Saturday October 20th, 09:00-11:00). This will be a new exam, i.e. all grades from the first exam will be reported to the Prüfungsamt. According to the Exam Rules (Prüfungsordnung), the second exam cannot be used to improve the grade on the first one (III. Paragraph 11 (7) of the Prüfungsordnung).

The second exam will be similar to the first one, but bonus points from the homework will not be counted; the grade will be determined solely by the result on that exam. This restriction rule will not apply to those who missed the first exam for a properly documented health reason (see III. Paragraph 11. (5) Satz 4--7 of the Prüfungsordnung). (In particular, one has to participate in the first Klausur to be allowed to participate in the second one.)

Exercise Sheets:
Will be posted on the web every Tuesday by 20:30 (8:30pm) on the exercise homepage. Solutions are due the following Tuesday at 18:00 (6:00pm) (sharp!) in the designated box. First sheet is posted on April 17th. For more details, see the exercise homepage.

The lectures, the webpage and our main literature are in English. The purpose is double: to strengthen the English knowledge of the German students and to make the lectures accessible to non-German Master students. The exercise sessions are also held in English, by default. However, Dr. Michelangeli and Prof. Sørensen (and all tutors) are ready to switch to German in private discussions. If you feel that your English is not strong enough to ask questions, please do it in German. The questions on the Exercise sheets and on the Klausur will be in English, but the solutions can be turned in either in German or in English.

There will be no comprehensive Skript (Lecture Notes), since we mainly follow excellent textbooks. The course will not follow a particular textbook. The list below provides a short selection of English and German textbooks on the subject (of which there are many!). Note that most of them cover the material of a two-semester course. The brief contents of the lectures will keep you updated, here you will (maybe!) find the more precise references.
