The Math Major and Minor
The Undergraduate Catalog lists the requirements of the Math Major. The Catalog also lists the requirements of the Math Minor.
Here we describe the requirements more informally.
Both the Math Major and Minor require a student to complete the pre-major requirements. These include the calculus sequence, a computer science or statistics course.
The major has some expectations on how a student fulfills their general education requirements. In particular there is an expectation of a one-year science course chosen from a select list.
The Bachelor in Science of Mathematics and Mathematics 7-12 Bachelor of Science degrees are available. The latter requires an additional 24 credits in an Education Sequence and some required elective upper-level courses (below).
Non-elective upper-level courses
To earn a Major in Mathematics there is an expectation of nine upper-level math courses beyond the pre-major. Six of these courses are required and described below. These courses are offered on a regular basis.

MTH339 Abstract Algebra
Group theory and ring theory allow one to analyze a variety of problems in mathematics and computer science from the viewpoints of abstraction and application. For example, students may prove basic results in group theory and apply these results to codes that are used on computers.
MTH341 Advanced Calculus I
These courses provide the theoretical basis of modern analysis by taking a more general look at the key concepts of calculus including continuous functions, differentiable functions and integration theory
Elective upper-level courses
Majors need 3 upper-level elective courses chosen from among the following. These courses are offered on a rotating basis.
MTH306 History of Math
Learn about mathematics by studying the development of mathematical ideas and techniques from antiquity through the eighteenth century. Topics involve arithmetic, algebra, trigonometry, and analytic geometry and will be drawn from Babylonian, Egyptian, Greek, Chinese, Hindu, Arabian and European mathematics.

MTH337 Combinatorics and Graph Theory
Many problems of a discrete nature, such as finding optimal postal routes and frequency assignments, are analyzed with graph theory. This course introduces the basic framework and shows how different problems can be solved within this.
MTH 342 Advanced Calculus II
Continuation of MTH 341
MTH 347 Number Theory
Problems from many branches of mathematics often reduce to the investigation of properties of a particular set of numbers; for example, the set of integer solutions to a certain equation. This course covers many elegant results from number theory, including some applications to cryptography.
MTH 349 Introduction to Cryptology
Cryptography is the study of concealing information, and is often called encryption and decryption. Cryptology is the study of the principles, techniques, other uses, and history of cryptography. This includes cryptanalysis, the study of breaking encryption schemes and finding weaknesses in security. In this course, the student will learn several historical cryptosystems and the modern math one would use to break them. This course has substantive overlap with MTH 347 (Number Theory), MTH 339 (Abstract Algebra), and MTH 311 (Probability).
MTH 350 Logic
What is an algorithm? When is a function computable? When is a question decidable? Computability theory, a part of logic, shows that some functions are not computable and some questions are not decidable.
MTH 370 Operations Research
Many decision-making problems can be modeled as linear optimization problems with constraints. Simplex method is used to find optimal solutions for these problems. Transportation problem is discussed as well.
MTH 372 Practical Machine Learning
Amazon's and Netflix' recommendations. Google's automatic translations. Siri, Alexa, Google Assistant and Cortana. All of these run on a common set of technologies: Machine Learning. Using a blend of software engineering and modern statistics, Machine Learning algorithms extract patterns from (possibly very large) data sets and generate likely functions that describe these patterns.
In this course, we will learn the basics of Machine Learning through hands-on implementation. By participating in competitions on Kaggle we will learn how to build a Machine Learning algorithm using the standard tools in the field as well as the theory that fuels the methods in the first place.
The course covers supervised and unsupervised learning, clustering and regression problems, and takes you through team work through 4 different competition tasks to build Machine Learning pipelines to take you all the way from raw data to predictions with prediction quality scoring.
MTH 410 Mathematical Statistics I
Statistics and Probability are closely coupled fields that deal with uncertainty and undeterministic processes in a way most mathematics does not engage with: Probability gives us a language and toolbox to model randomness and uncertainty, while Statistics gives us a toolbox to match probabilistic tools to concretely observed data as well as the ability to quantify our degree of certainty and perform quality control on our models.
In this course, we study statistics from a mathematical foundations perspective. Starting with the problem of how to estimate unknown quantities, and the ways that we can describe the quality of our estimators, the course continues to a formal theory of hypothesis testing and derives most tests that occur in a practical statistics course directly from properties of estimators and tests generated from them.
Many statistics courses will tell you how to test a claim using data. This course will tell you why these tests work.
MTH 411 Mathematical Statistics II
Continuation of MTH 410
MTH 415 Mathematical Biology
This course involves the growing interaction between mathematics and the biological sciences and provides a practical context for the mathematical description

MTH 442 Abstract Algebra II
Rings, integral domains, fields. Introduction to Galois theory.
MTH 445 Differential Geometry
Differential geometry is a mathematical discipline that uses the methods of differential and integral calculus to study problems in geometry.
Using the analytical tools of calculus, Euler and Lagrange were able to understand what are the curves on a surface that minimize the distance between two points. A main question is how those curves can be determined by using intrinsic measurement of the surfaces. In that direction, Gauss in 1825 made some fundamental contributions to theory of surfaces. His papers contain practical calculations of the curvature of the earth based purely on measurements made on the surface. He considered also properties of surfaces which are determined only by the geodesic distances between points on the surface independently of the particular way in which the surface is located in the ambient Euclidean space. This led to his Theorema Egregium, a fundamental result which explains why there cannot be an accurate planar map of the world.
Differential Geometry allows also to explain and describe the beautiful surfaces created by playing with soap bubbles. They are in fact examples of "minimal surfaces", a family of geometrical object that turns out to be quite relevant in applications. The above picture is the famous “catenoid” already studied by Euler.
In the applied world, Differential Geometry allows to design shapes used in everyday life, and is helpful when looking for a minimal path on curved surfaces. In physics, it allows to describe complicated physical systems leading to the Lagrangian formalism and General Relativity. The success of these theories makes Differential Geometry one of the fundamental tools in modern physics.
