Exponential Sums as Discrete Fourier Transform with Invariant Phase Functions
We give estimates for exponential sums over finite fields in several variables. We study the case where the phase is either quadratic or more generally invariant under the action ...

Relations Among Lie Formal Series and Construction of Symplectic Integrators
Symplectic integrators are numerical integration schemes for hamiltonian systems. The integration step is an explicit symplectic map. We find symplectic integrators using universa...
