Head of the team : Thomas Fiedler. Permanent members.

The research themes present in the team are very diverse:

• Derived algebraic geometry and homotopy theory

• Real and tropical algebraic geometry

• Geometric group theory and Teichmüller theory

• Non commutative geometry

• Riemannian and hyperbolic geometry

• History and philosophy of mathematics

• Number theory

• Singularity theory

• Algebraic topology and homological algebra

• Low dimensional topology

• Symplectic and contact topology

Interactions with other teams of the IMT :

• Dynamics and Complex Geometry : through complex algebraic geometry and differential Galois theory

• Analysis : through analysis on manifolds

Team Life :

The team meets for two major weekly seminars, "Geometry and Topology" on Tuesday morning and "Homotopy in Algebraic Geometry" on Tuesday afternoon, as well as three day-long conferences in "History and Philosophy of Mathematics" each year.
