Number Theory is one of the oldest branches of modern mathematics. It is motivated by the study of properties of integers and solutions to equations in integers. Many of its problems can be stated easily, but often require sophisticated methods from a diverse spectrum of areas in order to study. Its modern formulations are wide reaching and have close ties to algebraic geometry, analysis, and group theory; together with computational aspects. Perhaps due to the fundamental and profound nature of the integers, Number Theory plays a special role in mathematics and applications: two of the Clay Millennium Prize Problems are in Number Theory, and many internet security protocols are based on number theoretic problems.

Number Theory is an active area of research for faculty at SFU, and together with faculty at UBC, we form one of the largest communities of Number Theory researchers in North America.

Undergraduates interested in learning Number Theory can take MATH 342 Elementary Number Theory, which serves as a general introduction with minimal prerequisites. However, because research in Number Theory requires techniques from many areas, we encourage students interested in continuing in this area to take a broad spectrum of courses from our curriculum. For further guidance, please contact the Undergraduate Advisor.
