Course Description
A study of algebraic structures with emphasis on groups, rings, and fields. Prerequisite: Mathematics 230. (Under the old GEC, this course meets the Natural Science & Mathematics requirement.)Abstract Algebra: Theory and Applications by Tom Judson.
The textbook is an open-source book, you can download it free at the textbook's website. If you prefer a hardcover version of the book, the book can be ordered at the Lake Forest bookstore or it can be ordered online at Amazon or at Barnes and Noble for the inexpensive price of $20.
The following books have been placed on reserve in the library for more references:Topics we will cover
We will cover basic group theory, i.e., groups, subgroups, cyclic groups, permutation groups, cosets, Lagrange's theorem, Euler's theorem, group actions and basic ring theory. If we have time we'll also cover Sylow's theorems.
The course grade will be based on:
Homework 20%,
Midterms 45% (15% each),
Final Exam 35%.
There will be written homework roughly every week. All homework assignments can be accessed here. The homework assignments require a username and password. Your username is "lakeforest\username" (where you place username with your Lake Forest account username), and the password is the password from your Lake Forest account. The due dates for each homework assignment will be updated as the semester progresses. Each homework assignment will consist of roughly 10 problems I want you to work on. I provide the solutions for several of the problems. The problems without a solution are the problems you must turn in. Each student will submit the solutions to the problems written in LaTeX. Collaboration on the homework is permitted (and encouraged), however the solutions turned in must be written individually. You are not allowed to use the internet or any book not listed in the textbook section above to answer the homework exercises. Furthermore, the homework submissions must be your own. I take plagiarism seriously.
LaTeX Resources
As described above, the homework assignments should be written in LaTeX (and compiled to a pdf).
The tentative dates are:
Attendance
Students are expected to come to every lecture and every exam.Description of instructional time and expectations:
This course meets 3 times per week for 3 hours per week. The course carries 1.0 course credit (equivalent to four semester credit hours). Students are expected to devote a minimum of 12 hours of total work per week (in-class time plus out-of-class work) to this course.Academic Honesty
Academic honesty is expected of all students - and faculty. It is a central norm of academic life. Plagiarism is a serious violation of this norm. The scholarship you produce is the key determinant of my evaluation of you as a student. Therefore, if the words and ideas of others are represented in your work as your own - or if you recycle an earlier piece of your writing without indicating as such - you are committing academic fraud. You should assume that your work is being monitored for all possible plagiarism. Cases of fraud will be penalized, with outcomes ranging from an "F" for the offending assignment to an "F" for the course, and including a hearing before the Academic Honesty Judicial Board and the notification of the Dean of Students. Please refer to this helpful guide on the Writing Center page, and educate yourself about plagiarism and how to prevent it. You are obliged to discuss with me any concerns you have about whether your work conforms to the policy. See the Lake Forest College Statement on Academic Honesty and Plagiarism and the Academic Honesty section of the College Catalog for more information.
