Weakly, a set of problems will be posted
here. These are usually five to seven problems related to what we have
discussed in class. You are supposed to think about all of them and try
to solve them. You have to write a prcise solution for one or two of
those. If you have an idea for solving other ones, write them too.
More instructions will be given together with the problems. I will try
to post the problems on Friday each week and I will collect them the
next session.
