Handwritten note uploaded here. Should be correct, after I fixed a detail on what is required. I bet some of you submitted a much nicer phase plane sketch than mine.

And, Kolmogorov decided to award the lottery prize to G?ril. Congratulations.

Various messages: a correction; that lottery; availability; ...?

First, concerning the exam: I assume everybody knows that the exam is open-book, and that by now you have gotten used to the new location.
The problem set is English only, but - see the first link - you can write your papers in Norwegian, Swedish, Danish or English.
The solution note for 2016 had the sign of the beta in 4(b) wrong. I hacked the PDF and uploaded, but you do not need it if you just change the sign "by hand".
Availability before the exam: Tuesday (the day before the exam), I (Nils) have a Mathematics 2 review 1015-12 and possibly extended as long as they need it, but after that I will be available. Thu+Fri+Mon: drop by, or send e-mail to be sure. ...

Review lecture the 12th of May

You requested a review lecture then. 1015 appears to be fine with you. I have one minor reservation for the time, but let us schedule that.

Usually I cover the most recent exam. It is now uploaded together with a note from the grading committee; no formal guideline was written then.

Another update for the seminar problems

(English from now on.)
Concerning the 5150 problem, I had to update the text again. Stability of 2nd-order equations will require Monday's lecture, and maybe we should not focus on the case that is stable but not asymptotically so.
As pointed out in the now-deleted message in Norwegian: You shall not deduce the equation nor worry where it emerges from (though, take note that 0<p<1), and you shall not deduce K; just take it to be a constant. Also, for a particular solution when p=1/2: see the hint.
