Spring 2020


Prerequisites: Math 8201 or its equivalent.
Instructor: Victor Reiner (You can call me "Vic")
Office: Vincent Hall 256,
Telephone (with voice mail): 625-6682,
E-mail: reiner@math.umn.edu 
Classes: Mon-Wed-Fri 9:05-9:55am, Vincent Hall 364. 
Office hours: Mon and Wed 8:00-8:50am, Thurs 9:05-9:55am.
Also by appt., but Tues pm greatly discouraged
Required text: Abstract algebra, 3rd edition, by D.S. Dummit and R.M. Foote, Wiley, 2004.
Course content: This is the 2nd semester of the Math 8201-2 one-year graduate core sequence in abstract algebra.
Math 8201 dealt with groups, vector spaces, linear and multilinear algebra including spectral theory,
covering roughly these parts of the Dummit and Foote Chapters 1-6 and 11.
Math 8202 discusses rings, modules, and field theory, covering these parts of the text:
Chapters 7,8,9 on rings
Chapters 10,12 on modules
Chapters 13,14 on fields
and if there's some extra time, dip into Chapters 15, 17 and/or 18.

Dept. written prelims: One role of this class is to prepare the students for the Math PhD program's Algebra Written Prelim Exams.
Although we will go a long way toward this goal, those who intend to take the
prelim exam should not miss Paul Garrett's Abstract Algebra page,
containing links to his book for the class, solutions to many of the typical prelim exam problems, etc.
Homework: There will be homework assignments due every two weeks on Wednesdays at the beginning of class; see table below for assignments. There should be a total of 6 assignments, which will count for 35% of the course grade. The assignments will mainly be exercises from the book. Late homework will not be accepted. I encourage collaboration on the homework, as long as each person understands the solutions, writes them up in their own words, and indicates on the homework page with whom they have collaborated.
Exams:  There will be two take-home midquarter exams, posted later, each contributing 20% to the grade. There will be a take-home final exam, posted later, worth 25% of the grade. In contrast to the homework, there is to be no collaboration allowed with other humans allowed on any of the take-home midquarter or final exams.
