- Prerequisites: Either MATH 416 or one of ASRM 406, MATH 415 together with one of MATH 347, MATH 348, CS 374; or consent of instructor.
- Textbook: Frederick M. Goodman, Algebra: Abstract and Concrete version 2.6. This e-book is available free of charge: website for the book.
- Description: This course is an introduction to the modern abstract theory of algebra and algebraic structures. The primary focus is on the theory of groups, which are “abstract groups of composable transformations;” key examples include the symmetries of a geometric figure, and the permutations of a set. Our focus is on constructing groups, understanding their structure, and developing techniques for classifying them. At the end of the course we also begin the study of rings and fields, which are “abstract number systems” in which there are abstract versions of the four arithmetic operations: addition, subtraction, multiplication, and (in the case of fields) division.
- Lectures: Lectures will be held in person. Written notes for the lectures as well as videos (recorded in Spring 2021) are also available. Please see the links in the schedule below. The lectures do not correspond exactly to the class periods. For instance, in the first week of class the two lectures “Symmetries” and “Permutations” will be spread over Monday, Wednesday, and Friday.
- Homework: There will be 11 homework assignments whose due days (usually Fridays) are listed in the schedule. Homework must be submitted on paper in class. There is no homework due on weeks when there is an exam.
- Exams: There will be two midterm exams and a final exam. The midterm exams will be held in class on Friday October 1 and Friday November 5.
- Covid protocols: Througout this course we shall comply with all campus guidelines and rules regarding Covid-19, including rules on face masks and building access. Do not come to class if you are feeling ill or have tested positive for Covid-19. Please note that attendance does not count towards your grade in this course. If your absence means that you will miss an assignment or exam, please let the instructor know so that alternative arrangments can be made.
- Assessment: Grades will be based on homework (25%), two midterm exams (22% each), and the final exam (31%). The two lowest homework scores will be dropped. Grade cutoffs will never be stricter than 90% for an A- grade, 80% for a B-, and so on. Individual exams may have grade cutoffs set more generously depending on their difficulty.
- Late homework will not be accepted, but the lowest two scores are dropped, so you may miss one or two assignments without penalty.
- Missed exams: If you need to miss an exam (for reasons such as illness, accident, or family crisis), please let the instructor know as soon as possible. You will be excused from the exam so that it does not contribute to your final grade (there will not be a make-up exam).
- Collaboration and Academic Integrity: For homework assignments, collaboration is permitted and expected, but you must write up your solutions individually and understand them completely. On exams, no collaboration is permitted.
- Disability accommodations: Students who require special accommodations should contact the instructor as soon as possible. Any accommodations on exams must be requested at least one week in advance and will require a letter from DRES.
- Homework assignments should be submitted on paper in class on the due date. If you are unable to come to class, you may turn in your homework to James Pascaleff’s mailbox in 250 Altgeld Hall. This mailbox will be checked at 11:00am on the due date, so you should have your homework in the box by that time.
