Number theory group

Number theory group of UMPA.

The research subjects of the members of the Number Theory group are in the domain of arithmetic geometry, going from number theory to algebraic geometry. They cover several branches of arithmetic geometry, such as Galois representations, p-adic problems such as the p-adic Langlands program and p-adic cohomologies, motivic aspects that include K-theory and L-functions, and also algorithmic number theory and applications to cryptography.
