Symplectic integrators in sub-Riemannian geometry: the Martinet case
Monique Chyba, Ernst Hairer, Gilles Vilmart
We compare the performances of symplectic and non-symplectic integrators for the computation of normal geodesics and conjugate points in sub-Riemannian geometry at the example of t…
Solution of the time-harmonic Maxwell equations using discontinuous Galerkin methods
Victorita Dolean, Hugo Fol, Stephane Lanteri +1
We present numerical results concerning the solution of the time-harmonic Maxwell's equations discretized by discontinuous Galerkin methods. In particular, a numerical study of the…
A VFRoe scheme for 1D shallow water flows : wetting and drying simulation
Abdou Wahidi Bello
A finite-volume method for the one-dimensional shallow-water equations including topographic source terms is presented. Exploiting an original idea by Leroux, the system of partial…
The Multi-Dimensional Refinement Indicators Algorithm for Optimal Parameterization
Hend Ben Ameur, François Clément, Pierre Weis +1
The estimation of distributed parameters in partial differential equations (PDE) from measures of the solution of the PDE may lead to under-determination problems. The choice of a…
The complexity of class polynomial computation via floating point approximations
Andreas Enge
We analyse the complexity of computing class polynomials, that are an important ingredient for CM constructions of elliptic curves, via complex floating point approximations of the…
