Textbook: Abstract Algebra, by Dummit and Foote, Third Edition, 2004.
Here is the official syllabus. But everything you need to know about the course is on this webpage.
Description: This is an introductory course in modern algebra. Fundamental objects in modern algebra such as groups, rings, and fields will be introduced. There will also be a focus on learning to write proofs.
- Weekly problem sets will be posted here. Homework will not be graded, but there will be weekly quizzes based on the homework.
There will be a quiz at the beginning of class every Friday, starting February 2 (except weeks during which we have an exam, and April 27). The quizzes will consist of one problem from the previous week's homework. There will be 10 quizzes, but only your 9 highest scores will be counted when determining your final grade.
There will be two midterms given in class and one final exam.
- Exam 1:
- Covering: Sections 0.1 - 0.3, 1.1 - 1.3, 1.6, 2.1 and 2.3 (i.e. everything covered in class up through Theorem 20).
- Exam 2:
- Covering: everything between Section 2.4 of Dummit-Foote and the statement of the Fundamental Theorem of Finite Abelian Groups.
- Final exam
- Location: Ingraham 222.
- Covering: entire course, with emphasis on material covered since Exam 2.
PiazzaThis course will have a Piazza site; it is accessible through Canvas. This is a good place to ask questions about the homework, or general logistical questions about the course. Questions can be answered by other students or by me, and the answers will be visible to all students.
When asking questions, it is essential that you are precise and that you give as much context as possible. For instance, rather than asking: "I'm stuck on Homework Problem 4", explain what you've tried and where exactly you got stuck.
Outline of CourseMy current plan is to cover the following sections of the textbook: 0.1 - 0.3, 1.1 - 1.3, 1.6, 2.1 - 2.4, 3.1 - 3.3, 3.5, 4.1 - 4.3, 5.5, 7.1 - 7.4, and a selection of topics from Chapters 8 and 13. But this is subject to change.
Students taking the course with an honors component will be expected to do some additional reading (Section 4.5) and complete an additional problem set (which will be posted below later). Solutions to these problems will not be handed in; instead, we'll meet one-on-one, and I'll ask you to write out solutions to a selection of these problems on a chalkboard. This meeting will take roughly 30 minutes, and it will be scheduled sometime in April. Whether or not you earn honors credit for the course will depend on the extent to which you demonstrate to me during this meeting that you've understood these problems and their solutions.
You might find these problems challenging. I encourage you to start working on them early and to meet with me if you're having trouble solving them.
