I will be out of ¡­

I will be out of the country all of week 38, so there will be no regular lecture or exercise session Sept. 18-19. However, I suggested that the students meet Tuesday Sept. 19 for an excercise colloquium at the usual time and place, and I hope you all will find this helpful. For possible problems to discuss, see "Ukeoppgaver" for Sept 19.

The next regular lecture wil be Monday September 25, when I will start on section 5, "Distance in H".
