Again: The exam is open book, not only “book”; you can bring any written or printed material (and you can write on and annotate your printed material).

No matter what the teaching plan once said: the exam is Monday.

... and a note for seminar 10, as the ones on Nils's office door are all gone.

Math 2 and Math 3 review lectures: There will be review lectures on December 6th, auditorium 7: Math 3 at 1015, Math 2 at 1215 (i.e. the usual Math 2 time and place). Topics:

  • Most recent exam reviewed
  • 'Course in a nutshell'
  • Topics you request; please send me an e-mail – and please mark it with 'Math 2' or 'Math 3', OK?

I forgot to announce that you could pick up Bjorn's solutions to last week's problems. Please find them on my door, room 1243. – Nils.

A few messages:

  • Q: Review lecture? When? For Tuesday's lecture, please look up your (other) exam dates.
  • For next Tuesday – the lecture! – do problem 9-16. I'll cover it in class.
  • Monday's seminar is postponed one week. The final seminar is Thusday 22nd and Monday 26th. Problems posted.
  • I have made available the 2011 exam (as well as a note on the solution); if you have not seen it before, I suggest you allocate three hours for it.
  • Re your termpapers; as mentioned in class, I might have made some Kuhn–Tucker related remarks in the wrong place, arguing for the extreme value theorem in a problem where it does not apply. Please, by all means ask if I have left confusing comments.

I messed up the problems, pasting in some that had already been covered. New 10-x problems now posted. – Nils.

I'm done with your term papers (I still accept more of them!). They are very briefly annotated, but you should all read the following general remarks and see for yourselves whether they apply to you.

  • Some of you give references to the text book. That is of course fine, but if you know the result then you need not spend those minutes finding the proper reference. It is not required on the math exams. It is however an idea to spend a word when applying a known result, e.g. "by the extreme value theorem".


Re 2003 problem 2:

  • You fared well on this.
  • Notice that part (c) tells you to verify a particular solution. Having done that, you can solve (b) by solving the corresponding homogeneous.


Re 2003 problem 3:

  • Only a couple of you mentioned the constraint qualification. Fair enough. If you need that on an exam, we'll be precise abou...

Re the student manuals (PDF): The publisher has changed the web sites for the book series following new editions, but there is still one webpage up where student's manuals are available. Download links:

Someone asked how I wanted answers to the demand for higher courses. I intended you to write on the forms; if you didn't, then by all means send me an e-mail, preferably today. – NCF

  • I made a mistake of not updating the text for the term paper problem set. Of course there is no lecture on Thursday, and my intention was anyway next week. Updated version: next Wednesday.

  • PDFs for today corrected.

Published Oct. 13, 2012 1:12 PM

I posted a PDF for Tuesday. Review and an overview of how to handle the 2-dimensional system. (Everything new will be on the board in the lecture as well.)

Link to problem set corrected.

  • Next week is teaching-free, despite the 'time and place' document claiming the contrary (I do not have write access to that).

  • It was brought to my attention that some cell phone calendars have diverging week enumeration: for the record, this is week 40.

  • Problems for wk 42 now available. Quite a few, since you have two weeks.

  • I also put up a voluntary term paper problem set. It is a bit easy for exam problems (I've picked problems you can solve at this stage). What about submitting in ... wk 43-ish? I suggest you do not look at the problems until you can allocate a 3 hour exam-alike framework for yourselves.

  • Problems for wk 40 now available.
  • I was made aware that the information economics problem had wrong equation numbers (I should maybe take a hint that nobody has notified me before ...). I have corrected that mistake -- and a couple of other minor issues -- and put up a new version. It will likely not be prioritized for next week either, but you might have a look at it for the teaching-free week.
  • One of you requested a bit more on the application to portfolio choice. Last year I made a problem out of it; it is fairly close to the exposition I gave in class last week, but you might have a look if you are interested.

Hard to tell after wiping the board, but:

  • I might have written that volume was sum of the areas. Should be sum of (area * slice thickness). Slice thickness Δr tends to dr.

A couple of remarks re next week's problem set:

  • 3-19. Here, checking existence could be (too?) hard.
  • 3-13, my additional question: I overlooked that this is maybe a dumb one. See if you can spot why.

  • What is left in nonlinear programming, to be covered the uppcoming week: Constraint qualifications, sufficient conditions, special cases including mixed constraints, and sensitivity / the value function.

  • There should be PDFs out Monday by noon. Likely none for Wednesday.

  • Please share your thoughts about these slideshow-sessions parts of the lectures; both whether this is a good idea per se or not, or whether I should expand or limit the use (and: is it better suited for review, for presentation of 'this is where we are going', for theory walkthroughs, for 'nice to know for applications, but not relevant to this exam'?)
