Plenary exercise session

On Fridays 9.15-10.00 Aliaksandr gives solutions to as many as possible of the exercises, but sometimes he can not manage to discuss all of them during the plenary exercise session. Some solutions will be given under "Exercises" on the web page of the course after  this session. If there are particular exercises that you would like to see the solution of, please send him an email at aliaksah@math.uio.no before Thursday.
