This course covers the fundamentals of abstract algebra: groups, informal set theory, relations, polynomials, together with some applications: error correcting codes, Burnside's theorem, computational complexity, Chinese remainder theorem. This course is offered as both AMS 351 and MAT 312.
Textbook
Numbers, Groups and Codes (2nd Edition), Humphreys and Prest.
The first midterm will take place in class on Friday, Feb 25 (in class). It will cover all Chapter 1 of the textbook ("Number Theory"). To prepare for the exam, please review HW13, and the sample midterm .
The second midterm will take place in class on Friday, Apr 8. It will focus on groups (All of Chapter 4, and 5.15.3). See the sample questions for Midterm 2 (this is longer than the actual exam). Solutions to the sample exam.
The final exam (Friday, May 13, 11:15am1:45pm) will cover the material from Midterm 1, Midterm 2, and the Chapter 6 on polynomials. Here are holutions to a practice final.
There will be 2 midterms and a final. We will have 11 homework assignments.
The exams count for 75% of the final grade. The division is : 35% for the final and 20% for each midterm. The remaining 25% will be for the homework assignments.
No late HWs, and no makeup exams. (There will an extra makeup HW in case you missed one HW assignment).
