Pure Mathematics

The group of pure mathematics works with the theoretical problems arising in algebra, geometry and analysis, which have important applications in mathematical physics, relativity theory, quantum mechanics, coding theory and computer science, topology and number theory. Algebraic and differential equations are important tools of the research, which are carried on both abstract and computational levels. Lie theory, which focuses on various forms of the symmetry, is also part of the group activity.   The Group manages the Sophus Lie Seminar
