Number Theory, MATH 455/655, Fall 2007

This is the home page and first day handout for MAT 455/655, meeting MW from 2:30 -- 3:45 in CBC-C114.  My name is Dr. Arthur Baragar, my office is CBC-B 308, and I can be reached at 895-0378. Important information announced in class will also be posted on WebCampus. The prerequisite for this course is MATH 330 (linear algebra).

Syllabus: This course is expected to cover the following topics in number theory:

Text:  A Friendly Introduction to Number Theory, third edition, published by Prentice Hall. The website for this text is at

Grading Scheme: This is the grading scheme for this course:

Exams one and two will have an in class component and a take home component.  Exam three is a take home exam.  The take home components are due the following Monday at the beginning of class.  The grading scheme for students taking MAT 655 will be slightly different. There is no preset corelation between numerical grades and letter grades.  A letter grade (without + or -), a report card, if you like, will be posted on WebCampus after every exam. The distribution of the "Uncommitted points" will be described in class. They are to allow flexibility in the grading scheme, and may go to, for example, special projects.

Office Hours: If you need to see me, please look for me during the office hours posted below, or please make an appointment. Office hours begin the second week of classes.

The morning office hour immediately follows my MATH 126 class, and is primarily intended for those students, though you are welcome to show up at that time too.  However, I may be  helping students in our classroom, rather than in my office, so do not be surprised if I show up late.  A good time to ask quick questions is in our classroom between 3:45 and 4:00.
