Course Description: This course is an introduction to modern algebra and its applications. You will learn about some of the central concepts of algebra in a rigorous and proof-oriented manner. A distinguishing feature of this course is that the abstract concepts are not studied in isolation. Instead, each topic is studied with the ultimate goal of a real-world application.
Topics: The four core topics to be covered in this course are: (1) groups and finite fields; (2) linear algebra modulo p, with applications to error correcting Hamming codes; (3) polynomial algebra, factoring algorithms, with applications to BCH codes; (4) some number theory, with applications to public-key cryptography. Additional topics will be chosen from the following, depending on interest: (5) permutation groups, with applications to counting problems; (6) monoids and semigroups, with applications to finite-state automata.
Prerequisites: Mat 2141 or 2341, Mat 2143 or 2343.
Textbook: W. Keith Nicholson, Introduction to Abstract Algebra, 2nd Edition. The textbook is available from the Agora Bookstore, 135 1/2 Besserer Street.
Course Work: There will be weekly homework, one or two in-class midterms, and a final exam.
