# Mathematics and Statistics

The goal of the Mathematics and Statistics Department is to enable students to analyze and organize information using quantitative and statistical tools, to reason and argue logically, to employ appropriate problem-solving strategies, and to communicate complex ideas clearly and efficiently.

## About the Major

Ancient thinkers recognized mathematics as the language of the natural world. Today we know it drives science and social science, business and industry, even art and design. Math majors at Hamilton explore both the abstract, theoretical aspects of mathematics and its applications to a variety of topics. The curriculum delves into the many branches of math, and courses foster deductive reasoning, persuasive writing, and analytical and quantitative problem-solving. Those who love math will find themselves among like-minded peers and mentors, talking shop outside their professors' offices and producing research that they may present at a professional conference. The department also offers a minor in statistics.

### Students Will Learn To:

- Use mathematical and/or statistical tools to model real-world problems
- Construct mathematical proofs based on rules of logical inference
- Communicate complete mathematical and/or statistical arguments

## A Sampling of Courses

### Graph Theory

An introduction to the theory and applications of graph theory. Topics include: trees; connectivity; Eulerian and Hamiltonian graphs; vertex-, edge- and map-colorings; digraphs; tournaments; matching theory; planarity and Ramsey numbers.

### Explore these select courses:

This course covers statistical methods in machine learning such as decision trees, random forests and support vector machines The course will use a project-based approach to give students hands-on experience using these techniques by analyzing large and complex real-world datasets. More importantly, they will learn the statistical principles behind these procedures, such as loss functions, maximum likelihood estimation and bias-variance trade-off as well as why these principles matter in real world settings.

Number theory is the study of the properties of the positive integers. Topics include divisibility, congruences, quadratic reciprocity, numerical functions, Diophantine equations, continued fractions, distribution of primes. Applications will include cryptography, the practice of encrypting and decrypting messages, and cryptanalysis, the practice of developing secure encryption and decryption protocols and probing them for possible flaws. Speaking Intensive.

Cockburn and McAvoy ’23 Explore Graph Automorphisms

Professor of Mathematics Sally Cockburn and Sean McAvoy ’23 worked on a research project exploring what happens when graph automorphisms that are usually applied to vertices are instead applied to edges.

Zhao ’23 Testing Theory About Rent Control Programs in Levitt Project

Many economists agree: like any form of price control, rent control programs are a bad idea. But Alan Zhao ’23 is not like most economists.
