A dynamic subject, with connections to many disciplines, mathematics is an integral part of a liberal arts education, and is increasingly vital in understanding science, technology, and society. Entry-level courses introduce students to basic concepts and hint at some of the power and beauty behind these fundamental results. Upper-level courses and the capstone experience provide majors with the opportunity to explore mathematical topics in greater depth and sophistication, and to delight in the fascination of this important discipline.
The department assists students planning to study mathematics in choosing an appropriate starting course. Based on a student's academic background and skills, the department recommends a 100-level course, MATH 205, MATH 206, or a more advanced course. For students unsure whether to start in MATH 105, 106, or beyond, the department recommends taking the online placement examination.
The mathematics department offers a major and a minor in mathematics. More information on the mathematics department is available on the website (bates.edu/mathematics).

Students are active participants, presenting material to one another in both oral and written form, and conducting individual research on related questions. Enrollment limited to 15. Instructor permission is required. [W3] Staff.
MATH 495D. Chaotic Dynamical Systems.One of the major scientific accomplishments of the last twenty-five years was the discovery of chaos and the recognition that sensitive dependence on initial conditions is exhibited by so many natural and man-made processes. To really understand chaos, one needs to learn the mathematics behind it. This seminar considers mathematical models of real-world processes and studies how these models behave as they demonstrate chaos and its surprising order. Prerequisite(s): MATH 301. Instructor permission is required. [W3] S. Ross.
MATH 495E. Networks.A variety of networks such as social networks of people in a community, neural networks of organisms, and the network of web pages in the World Wide Web can be represented using graphs from the field of graph theory. A graph is a collection of nodes in which certain pairs of nodes are joined by edges between them. Graph theory provides a framework for the study of properties of networks. After a basic introduction to graph theory, students choose a network or particular properties shared by different types of networks to study further through readings from books and research papers. Prerequisite(s): MATH 301. Enrollment limited to 15. Instructor permission is required. [W3] P. Jayawant.
MATH 495H. Cryptography.Public key cryptography is at the center of most secure transactions these days, from using a credit card online to sending and signing secure messages. The security of a cryptosystem relies on finding solutions to difficult math problems like factorization of large numbers and the discrete logarithm problem. After an introduction to the basics, each student studies various methods of encryption like the RSA cryptosystem, the Diffie-Hellman key exchange, Elliptic Curve Cryptography, and various methods of breaking these encryptions. These topics draw from previous knowledge in abstract algebra, analysis, geometry, and number theory. Computer algebra systems also are used to illustrate the applications. Prerequisite(s): MATH 301 or 309. Instructor permission is required. [W3] A. Salerno.
MATH 495J. Advanced Topics in Biomathematics.Biology is one of the most fertile sources of new mathematics. Research may be based on computation and data, or it may rely entirely on theorems and proofs. It may require calculus, linear algebra, graph theory, differential equations, or numerical analysis. Students in this seminar read biology-inspired mathematical research and present their findings to each other. Students' mathematical interests influence the selection of research papers to be investigated. No previous course in biology or mathematical modeling is required. Prerequisite(s): MATH 301. Instructor permission is required. [W3] [QF] M. Greer.
MATH 495L. The Fundamental Theorem of Algebra.Over the centuries, there have been numerous proofs of the Fundamental Theorem of Algebra (FTA), which asserts that every polynomial of degree n must have at most n distinct roots over the complex numbers. The great German mathematician Carl F. Gauss (1777-1855) published no fewer than four different proofs of the result. While the name of the theorem foregrounds algebra, none of the known proofs is purely algebraic. Over the centuries, techniques from complex analysis, topology, and field extensions have been employed to give new proofs of the FTA. In this seminar, students explore some of these proofs where the methods are drawn from various subfields in mathematics. Prerequisite(s): MATH 309. Enrollment limited to 15. Instructor permission is required. [W3] [QF] P. Wong.
MATH s33. Mathematics for Social Justice.This course teaches quantitative literacy, critical thinking and problem solving skills in a socially relevant context. Students use mathematics as a powerful analytic framework for understanding and developing realistic solutions to issues of social, political, and economic justice. The overarching goal of this course is for students to develop the ability and inclination to use mathematics to understand, and improve, the world around them. Prerequisite(s): MATH 106.
