Math 417 (Rezk, Fall 2020, Sections D13 and E13).

This is an undergraduate course on abstract algebra. It begins by
introducing various notions of algebraic structures, and then proceeds
to develop the theories of groups and rings.
The prerequisites for the course are linear algebra, and a course
which teaches the basics of reading and writing proofs, such as Math 347.
The course will be taught in person (events permitting). I am
teaching two sections of this course: D13 (meeting 11am-noon MWF) and
E13 (meeting 1pm-2pm MWF), both in Altgeld Hall 345. I will try to
keep the two sections as identical as possible.
- Lectures. Most class days will be lectures, but with
some breaks for discussion or group work possible.
- Readings. I'll list sections from the textbook to read
for each class day, if applicable. I will also post my lecture
- Lecture notes. I post lecture notes. (These may be
- Homework. Assigned weekly: you will find the
assignment on the homepage of the course. Due Mondays by 1pm
(CST), for both sections. Submission by paper is preferred, but I
will also accept online submission. (For online submission, scan
your papers using a phone scanning app such as Microsoft Lens or
Adobe scan which is designed to produce a legible .pdf.)
- Exams. Four midterms and a final. (Dates will be set
- Office hours. I will schedule at least 3 hours a week
for office hours. During office hours you can find me in my office,
or you can talk to me via Zoom, to answer any questions or discuss
anything you want. (Note: at
the start of the semester these office hours will be online only, as
my office is scheduled to be moved soon after term begins. I'll
start having in-person office hours as soon as I have a new office.)
The course is based on my lecture notes, as well as on a free online
textbook. The textbook is Goodman, Algebra: Abstract and Concrete
(Links to an external site.), edition 2.6.
