• For course assignments see the Canvas page.
• Office Hours: see my calender and/or by appointment
• Class meets:
  • MWF  11 am,  officially -- 145 Armory
• Prerequisites: Officially either honors section of math 416 or MATH 415 together with an honors section of MATH 347. In practice, ability to read and write proofs and some familiarity with induction, modular arithmetic and complex numbers.  In any case consent of the department is required.

Textbooks:
I will be following (to some extent)

• W. Keith Nicholson Introduction to Abstract algebra. Fourth edition, Wiley
  You may also want to look at
• David S. Dummit and Richard M. Foote Abstract Algebra.

We will study groups, rings and modules. So roughly chapters  1-5 and 7 of Nicholson.

• Homework: Homework problems are to be assigned once a week on Canvas.  Late homework will be penalized. There are several reasons why I want the homework to be turned in on time. First of all, if you are not keeping up with the homework, you are not keeping up with the class, and then you may well get lost in the lectures. Secondly, it is hard to grade fairly the homework that is turned in late. The grader would have to keep careful track of the grading rubrics and so on. In short: late homework is bad for you and means more work for the grader.    
  If you have questions about your homework score please take it up with the grader first. If you and the grader can't resolve the issue I will step in.
  If you have questions about the homework itself, please use  campuswire and/or see me in the office hours.  If you email me with a question about homework I may repost your question on campuswire and reply there.  

• Attendance: of lectures/discussions is expected. See student code, part 5

• Exams: There will be two midterms and a final. All exams will be closed book.

  The midterms will take place on March 5 and April 7 (the dates are not likely to change).

  The final, according to the non-combined final examination schedule is to take place at 8 am on Thursday, May 15.

  Requests for a make-up exam require a serious documentation and are almost never granted.

• Grade: The formula for the course grade is roughly as follows:
  • final exam = 36 %
  • 2 midterms at 22 % each = 44%
  • homework = 20%
