Also, here is my solution to the first part of HW6: (link)

The Midterm will be handed out in class/made available online Monday, May 7. It will be due Monday, May 14 at 2pm. 

Here are sample solutions for the midterm. 


The final is available here, and due Friday June 15 at 2pm. (In the file it says due 11:59am, but 2pm is fine).

The password has been emailed to you. If you have issues accessing the exam, please contact Meagan.

For the final, all representations/characters will be over C. You don't need to learn the general statement of the Artin-Wedderburn theorem, but you do need to know the consequences we derived from it over C, e.g. the character orthogonality relations.

* You may use a computer or calculator while doing the homework, but may not refer to this as justification for your work.  For example, "by Mathematica" is not an acceptable justification for deriving one equation from another.  Also, since computers and calculators will not be allowed on the exams, it's best not to get too dependent on them.
