The mathematics group at the Department of Mathematics, Aarhus University, is an active and internationally recognized research unit. We carry out research in a wide selection of areas of mathematics and its applications. This includes:

• Algebra • Algebraic, complex, symplectic and differential geometry • Algebraic topology and homological algebra • Computational mathematics • Dynamical systems • Geometric invariant theory • Geometric and algebraic representation theory • Harmonic analysis • Inverse problems • Number theory • Operator algebras and free probability • Partial differential equations • Spectral theory and mathematical physics.

The mathematics group has active collaborations both nationally and internationally and with many other scientific fields, including Computer Science, Engineering and Physics.
