Course description
This is the first half of a two semester sequence designed primarily to provide the algebraic background necessary
for the algebra prelim. The syllabus for the algebra prelim can be found
online; we will
aim to cover the sections on Groups and Rings and Modules, along with some supplemental topics if time permits.
Textbook
Dummit and Foote, Abstract Algebra, Third Edition.
Grading
Grades will be based on weekly problem sets (50%), a take-home midterm (20%), and the three-hour final exam (30%).
The midterm will be handed out on Wednesday, Oct. 5 and due the following Wednesday.
