John B. Fraleigh,   A First Course in Abstract Algebra,
                            6th edition, published by Addison Wesley, 1999


Introduction to the basic concepts of abstract algebra, with applications:
    groups (cyclic, symmetric, Lagrange's theorem, quotients, homomorphism theorems);
    rings (congruences, quotients, polynomials, integral domains, unique factorization);
    fields (field extensions, constructions with ruler and compass).


Algebra is the study of algebraic systems, that is, sets of elements endowed with certain operations.
A familiar example is the set of integers with the operations of addition and multiplication.

Algebra is used in almost every branch of mathematics; indeed, it has simplified the study of mathematics by indicating connections between seemingly unrelated topics. In addition the success of the methods of algebra in unraveling the structure of complicated systems has led to its use in many fields outside of mathematics.

One aim of this course is to help students learn to write clear and concise proofs, read the mathematical literature, and communicate mathematical ideas effectively, both orally and in writing.

Prerequisite: AS/SC MATH 2022.03 or AS/SC/AK MATH 2222.03

Problem Session:   TBA

SYLLABUS:   We will study the following sections:
                      Chapter 1:  Groups and Subgroups                         Sections 1--5
                      Chapter 2:  More Groups and Cosets                      Sections 1--4
                      Chapter 3:  Homomorphisms and Factor Groups     Sections 1--3
                      Chapter 5:  Introduction to Rings and Fields            Sections 1--2, 4--6
                      Chapter 6:  Factor Rings and Ideals                        Sections 1--2
                      Chapter 8:  Extension Fields                                  Sections 1--4

HOMEWORK:   There will be about 10 assignments.  You are expected to do  all of the assigned homework.  The only  way to learn algebra  is to do it!  The amount you learn in this course and the grade you receive will be proportional to the amount of time you spend doing problems.

EXAMS:    There will be two tests and the final exam.

    Tests:             2:30 p.m. Thursday, November 15 and February  7.
    Marks:           Each of the two tests 20%;  Final exam 40%;
                         Assignments, presentations and  class participation 20%.

MISSED EXAMS:  There will be no make-up exams for missed tests. Upon presentation of documentation of  a valid excuse, the corresponding percentage of the final mark will be added to the final exam. With no presentation of such documentation a grade of zero will be entered for the missed tests.
