COURSE DESCRIPTION
WHAT IS MATH 103A?
This is the first
undergraduate course in modern (abstract) algebra. In this course we will examine topics in group theory. We will
cover most material in Chapters 011 in the textbook.
TEXT Joseph A. Gallian Contemporary Abstract Algebra, Ninth Edition.
(Cengage Learning, 2017). You
are expected to read the text BEFORE each lecture. The students
enrolled in this class are expected to be familiar with the material
taught in Math 109 (Mathematical Reasoning), which is a background
requirement for Math 103A. Chapter 0 in your textbook reviews
some of the main topics in Math 109. Please read it on your own in
detail, as it will be covered only very briefly in class.

will not discuss mathematics (e.g. solutions or hints of solutions
to HW problems) via email. Office hours and lectures are the best venue
for that purpose. However, if you have any type of administrative
