Math 25800: Abstract Algebra
All reading and homework is from Dummit and Foote. Since I will make changes in the schedule, you should make a point of checking frequently to be sure you have the most up to date list of assigned problems and due dates.

The listed exercises should be handed in at the beginning of lecture on the due date indicated.

Note that there are two reading/review assignments on material from linear algebra.
