FYS 446 The Communication Equation: A Mathematical Media Tour

Mathematics is everywhere in the news these days, from basic statistics to more sophisticated uses to describe economics, science, and mathematical breakthroughs. Too often we accept numbers and data as the truth, without giving them a second thought. It is therefore important to develop critical reading skills. As creators of information, it also is important to learn to use mathematics and data to support arguments and undertake true scientific reporting. In this course students read breaking news articles and longer features to learn effective uses of mathematics in journalism. They put these best practices to use by writing articles, blogs, and radio pieces. Additional topics may include mathematics in other media such as fiction writing, television, movies, and art.

Additional topics include symmetry, frieze and wallpaper patterns, and tesselations.

FYS 533 Paperfolding: A Blend of Art, Mathematics, and Engineering

From the ubiquitous paper crane to hyperbolic surfaces to space telescopes, origami has exploded in the last fifty years. Origami continues to inspire artists who have moved well beyond birds into fantastically complex creations involving hundreds of folds. It has brought together scientists, mathematicians, artists, teachers, and engineers. In this course, students learn basic paper folding techniques to create simple origami designs. Then they use these designs to delve into the world of mathematics, from using origami to trisect an angle to exploring the Cut and Fold Theorem. Students also look at some of the folds that have led to applications in design and engineering. Finally, they consider the work of artists who have taken origami into high art, and investigate how origami is being used in the world of education.

Normally offered every year.

MATH 355A Numerical Analysis

This course studies the best ways to perform calculations that have already been developed in other mathematics courses. For instance, if a computer is to be used to approximate the value of an integral, one must understand both how quickly an algorithm can produce a result and how trustworthy that result is. While students implement algorithms on computers, the focus of the course is the mathematics behind the algorithms.

Topics may include definitions and properties of graphs and trees, Euler and Hamiltonian circuits, shortest paths, minimal spanning trees, network flows, and graph coloring. Some of the class meetings are devoted to learning to program in Maple. Students then write computer programs to provide solutions to questions such as the ones mentioned before. Prerequisite(s): MATH 221 or s21.

MATH 355D Dynamical Systems and Computer Science

The study of long-term behaviors of feedback processes, the field of dynamical systems is best understood from both theoretical and computational viewpoints, as each informs the other. Students explore attracting and repelling cycles and witness the complicated dynamics and chaos a simple quadratic function can exhibit. Real and complex functions are considered. Simultaneously, students learn sound computer science fundamentals by writing Visual Basic programs that illustrate the theory of dynamical systems. In particular, students plot both orbit and bifurcation diagrams, Julia sets, and the Mandelbrot set. The course explores both dynamical systems and computer science in depth, thus requiring four meetings per week. Prerequisite(s): MATH 221 or s21.

The development of the topic draws on students’ previous course work and helps consolidate their earlier learning. Students are active participants, presenting material to one another in both oral and written form, and conducting individual research on related questions.

MATH 495A Factoring in Numerical Monoids

Integers enjoy a key property: by the Fundamental Theorem of Arithmetic, every nonzero integer can be factored uniquely into a product of prime integers. What can we say about factorizations into irreducible elements in other algebraic structures? Does uniqueness always hold? If not, which tools can we use to measure how different the factorizations of an element can be? In this seminar, we explore numerical monoids, and we investigate several factorization invariants to measure how far factorizations are from being unique. Prerequisite(s): MATH 301 or 309.

MATH 495B Generalized Stokes Theorem

The famous theorems of Gauss, Green, and Stokes in multivariable calculus have many important applications in the study of electromagnetic fields, heat diffusion, fluid dynamics, and complex analysis. Moreover, they are all generalizations of the (one dimensional) Fundamental Theorem of Calculus. These results assert that a certain (k dimensional) integral over a region is the (k-1 dimensional) integral over the boundary of the region, culminating in the so-called Generalized Stokes Theorem. This seminar aims to explore this general form of the classical Stokes Theorem and related topics, including the concept of differential forms.

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.

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.

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.

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.

MATH 495M Infinite Series

An infinite series is the sum of the terms of an infinite sequence. In calculus we encounter infinite series of real numbers, for example, the geometric series. This course focuses on infinite series of functions, beginning with an introduction to function series and convergence. Students explore power series, Laurent series, and trigonometric series, culminating with an in-depth examination of Fourier series. Fourier series have numerous applications to areas such as partial differential equations, signal and image processing, acoustics and econometrics, to name only a few. Based on their interests, students investigate one or more of the aforementioned applications of Fourier series using current research papers and texts in mathematics and computer software. Prerequisite(s): MATH 301.

In this course, students learn how to play the SET game, explore mathematical ideas and questions related to SET, and discover the mathematics by working through investigations in small teams. This process enables students to enhance their reasoning, collaborative, and communication skills as well as experience the power of figuring out things on their own.
