Problem session instead of lecture Thursday May 11th

On Thursday May 11th, instead of the usual lecture (14-16), there will be a problem session in Origo. You are encouraged to work on PS13 (Partial differential equations). Unless there are many people needing help at the end, the usual problem session 16-18 is then cancelled.

There will also be problem sessions at the usual times for PS13 the following week, so last time on May 18th.
