Let M be a compact connected manifold of dimension n endowed with a conformal class C of Riemannian metrics of volume one.. Colbois : Universit´e de Neuchˆatel, Laboratoire

This method of calculation associating conformal transformation of the complex plane and multilayer matrix formalism provides a good approximation of the effective

The Z-plane corresponds to the real configuration where the waveguide is curved, on which the operation w=R ext .ln(z/R ext ) is applied prior to further calculations on

We develop and study stability properties of a hybrid approximation of functionals of the Bates jump model with stochastic interest rate that uses a tree method in the direction of

Calculation of a Multi-Port Scattering Matrix for the Acoustic Power Flow Using Finite Element Method.. Cyril Calmettes, Emmanuel Perrey-Debain, Emmanuel Lefrançois,

We first present the level set method, and then we derive from the previous analysis an iterative scheme which converges provided that the initial guess is not too far from
