Algebra is about abstracting and formalizing the properties of everyday mathematical structures. As such it forms a language well-suited to the study of mathematical objects, and interacts with many other branches of mathematics such as topology, geometry, dynamics, number theory, combinatorics, logic, etc. Among the various algebraic structures, groups play a particularly central role since they describe the symmetries (or automorphisms) of any object or system. Group theory features prominently among our faculty members' interests, whether it be through the study of group representations, that of the geometric aspects of groups, or a focus on specific classes of groups such as finite, algebraic or Lie groups.
