Textbook 
Groups and Symmetry, by M. A. Armstrong. 
Grade Breakdown  Midterms  20 % each, Final Exam  35%, Homework  25% (15% problem sets, 10% writing assignment) 
Course Content  We will follow Armstrong's book closely and cover most of the sections over the course of the quarter. We'll begin by introducing the notion of a group and then exploring many examples and subtleties of this definition. Some of the topics to be covered include subgroups, permutation groups, matrix groups, Lagrange's theorem, homomorphisms and isomorphisms, and lattice groups. We will conclude by discussing some of the applications of these concepts to physics, chemistry, and number theory. The evolving syllabus will contain further information. 
Prerequisites 
There are essentially no prerequisites for this course. We will build up to most of the more difficult concepts together in lecture. However, a decent background in linear algebra will be useful in dealing with several of our examples. Some familiarity with proofs and abstract mathematical thinking is a bonus, but not a requirement. Several evening supplementary sessions (completely voluntary) at the beginning of the quarter will provide the essential information on proofs and proof techniques for those who are unfamiliar with them.
