# MAT 534: Algebra I (Fall 2018)

### Announcements

**Midterm 1**will be held in class on Thursday, September 27.**Midterm 2**will be held in class on Thursday, November 15.- The
**Final Exam**will be held on Thursday, December 20, from 8am to 10:45am, in our usual classroom**ESS 183**.

### About the course

Abstract algebra is the study of algebraic structures such as groups, rings, fields, or vector spaces. In the course, we will study groups, rings and modules, and basic linear algebra. You can find a more detailed list of topics on this page.

### Textbook

The textbook for the course is “Abstract Algebra” (3rd edition) by David S. Dummit and Richard M. Foote. Please see the official syllabus for additional information about the course, including university-wide policies.

### Grading

The final exam for the course will be on **December 20**. We are also
going to
have two midterms (in class) and weekly homework assignments. Your grade will
be determined based on the final exam (35%), the two midterms (20% each), and
your homework (25%). The general policy is no make-up exams and no late
homework, but there will be an extra homework assignment at the end of the
semester to make up for any missed assignments.

### Time and location

We meet on Tuesday and Thursday, 10:00–11:20 am, in room **ESS 183**
(in the Earth & Space Sciences building).

### Office hours

My office hours are on Tuesday afternoon from 1:00pm–4:00pm.

### Schedule

Please read the corresponding sections before or after class.

### Homework assignments

There will be a written homework assignment almost every week. Please write up your solutions nicely, staple all the pages together, and hand them in during the following week, at the beginning of Thursday's class. Some of the problems will be graded ; the grader is Qianyu Chen. We are also going to discuss some of the problems in class on the following Tuesday; you are expected to participate in the discussion and, from time to time, volunteer to present a solution in front of class.
