If you have questions about your solution to the mandatory assignment or about the written comments to your solution you can come and discuss this with me during office-hours Tuesday April 10, from 11 to 12 or Thursday April 12 from 13:30 to 14:30.

One clarification about the text of the assignment: in problem 4, question e), by "pairwise distinct" it is meant that "xrH and xsH are not equal when r and s are different between 0 and l-1". Here "pairwise distinct" is equivalent to "pairwise disjoint".

An "orakel" service is offered for this course. More precisely, if you have concrete questions to the theory or exercises in this course you can send an e-mail to "". Write "MAT2200" in the subject of your e-mail.

At the drop-in hour on Tuesday January 24 you have the opportunity to ask questions about the exercises for this week. These exercises are: section 0 (29, 30, 31), section 2 (8, 23). Note: I dropped exercise 6 from section 2 and replaced it with exercise 8 from section 2.

For the time being the plan for the drop-in group looks similar to the plan for the Wednesdays lectures, except that it is shifted in date. I am trying to fix this problem.
