Asymptotic expansion of the voltage potential under small Robin perturbations of its boundary conditions
Eric Bonnetier, Charles Dapogny, Roman Moskalenko
Inspired by questions related to inverse problems and shape optimization, we derive an asymptotic expansion of the voltage potential, solution to a model elliptic second-order part…
On the {} norms of spectral projectors on shrinking intervals: the cases of some spheres of revolution and of the Euclidean disk
Ambre Chabert, Yves Colin de Verdìère
Given a compact Riemannian surface , with Laplace-Beltrami operator , for , let be the spectral projector on the bandwidth $[λ-λ^{-\frac{1}{3}}…
On the dynamics of leapfrogging vortex rings
Martin Donati, Lars Eric Hientzsch, Christophe Lacave +1
The evolution of highly concentrated vorticity around rings in the three-dimensional axisymmetric Euler equations is studied in a regime for which the leapfrogging dynamics predict…
Classical and Quantum mechanics on 3D contact manifolds
Yves Colin de Verdìère
In this survey paper, I describe some aspects of the dynamics and the spectral theory of sub-Riemannian3D contact manifolds. We use Toeplitz quantization of the characteristic cone…
Networks of sign-changing metamaterials: existence and spectral properties
Kaïs Ammari, Eric Bonnetier, Alessandro Duca
We study composite assemblages of dielectrics and metamaterials with respectively positive and negative material parameters. In the continuum case, for a scalar equation, such medi…
The long way of a viscous vortex dipole
Michele Dolce, Thierry Gallay
We consider the evolution of a viscous vortex dipole in originating from a pair of point vortices with opposite circulations. At high Reynolds number , the dipole ca…
