Welcome to MAT 312 --- Applied Algebra; Spring 2008.

This is an introduction to abstract algebra and applications. We will study basic properties of the integers and of abstract groups. We will also study public key codes and error detecting and correcting codes. This is a both a "proof course" and an applications course. So each student should try to understand all the proofs that are discussed.
