Concentrating his skills on two areas of excellence, algebraic geometry and arithmetic geometry (Lie theory, singularities, the Langlands program, computer algebra), the team is constantly developing attractive training, scientific links with the most major national and international institutions leading to scientific work of the highest level.
Research Topics
- Complex algebraic geometry. Quantum cohomology and K-theory, Fano varieties, varieties with group action,
Schubert calculus, spherical manifolds, Frobenius splitting.
Geometric study of functional or differential equations in complex fields (sheets, fabrics, etc.).
Modular spaces of flat surfaces, hypergeometric functions, complex hyperbolic geometry.
- Local standardization and desingularization of diagrams in positive characteristic and in arithmetic.
Associated invariants: tangent cones, polyhedra, graduated algebras. Effective calculations on singularities. Arc space on singular algebraic varieties.
- Complex and modular representations of Lie groups and algebras and p-adic reductive groups. Local Langlands correspondences and functorials. Representations of reflection groups and Hecke algebras. Invariants of nodes.
- Number of points, zeta functions, Frobenius distribution, infinite turns and asymptotic theory.
- Galois theory of functional equations.
- History of mathematics in the 19th and 20th centuries.
- Didactics of first degree mathematics.
