Abstract algebra and number theory are broad areas of mathematics which formalize intuitive notions of symmetry, and which explore properties of integers and other closely related number systems. Modern research in these areas includes the exploration of deep questions of a purely theoretical nature, as well as applications to data transmission, information security, physics, and other areas of science and engineering.
Algebra and number theory research faculty
At Oregon State, Clay Petsche researches connections between number theory and dynamical systems, equidistribution, and height functions over local and global fields. Thomas Schmidt studies number theory, the dynamics of continued fractions, and Fuchsian groups related to translation surfaces. Holly Swisher does research in number theory and combinatorics including modular and mock modular forms, partitions, and hypergeometric series. And Mary E. Flahive's work in number theory is principally in Diophantine approximation, with techniques from the geometry of numbers.
