COURSE DESCRIPTION 
This course is a first introduction to structures of abstract algebra, specifically, groups, rings, and fields. There will be a significant emphasis on reallife problems which are modeled by abstract algebraic structures. The first quarter of the course will be devoted to elementary number theory. Then, we will focus on group theory. This is the core of this class, and we will devote half of the course to this topic. We will end the class with an overview on rings and fields. Applications will be discussed within each topic. This class is proofbased. However, it is not expected that you have taken a proofbased course before, and there will be an opportunity to learn and improve proofwriting. In addition, there will be a significant emphasis on reallife problems which are modeled by abstract algebraic structures. There will be a final project on applications of group theory (e.g. cryptography, codes, music, physics, and Rubik’s cube). Project suggestions will be introduced during the first half of the semester. Prerequisites In addition to the common requirements, basic knowledge of sets, functions and equivalence relations is expected. Faculty Fall 2019
