Abstract Algebra 2

Schedule and Homework



Homework will generally be collected on Mondays, with a portion of each Friday class devoted to going over exercises. For the first half of the course, exercises will come from Stewarts Galois Theory . Note that the last exercise in each section is a set of True-False Questions that we will go over in class.
