Only digital lecture today, Wednesday 25/8

I have a sore throat today and can not come to give the lecture. I will give the lecture on Zoom from home instead, normal time at 12:15-14. Tomorrow we will have lecture instead of problem solving as announced. If I can come, it will be in Kristian Birkelands auditorium, otherwise on Zoom, please check for new messages and I will update the information (I try to figure out if I can come with light symptoms in case my test is negative) .
