Computing effectively stabilizing controllers for a class of D systems
Yacine Bouzidi, Thomas Cluzeau, Guillaume Moroz +1
In this paper, we study the internal stabilizability and internal stabilization problems for multidimensional (nD) systems. Within the fractional representation approach, a multidi…
Variational projector augmented-wave method: theoretical analysis and preliminary numerical results
Xavier Blanc, Eric Cancès, Mi-Song Dupuy
In Kohn-Sham electronic structure computations, wave functions have singularities at nuclear positions. Because of these singularities, plane-wave expansions give a poor approximat…
Domain decomposition preconditioning for the high-frequency time-harmonic Maxwell equations with absorption
Marcella Bonazzoli, Victorita Dolean, Ivan G. Graham +2
This paper rigorously analyses preconditioners for the time-harmonic Maxwell equations with absorption, where the PDE is discretised using curl-conforming finite-element methods of…
Spectral approximation of elliptic operators by the Hybrid High-Order method
Victor Calo, Matteo Cicuttin, Quanling Deng +1
We study the approximation of the spectrum of a second-order elliptic differential operator by the Hybrid High-Order (HHO) method. The HHO method is formulated using cell and face…
Multiscale Finite Element methods for advection-dominated problems in perforated domains
Claude Le Bris, Frederic Legoll, Francois Madiot
We consider an advection-diffusion equation that is advection-dominated and posed on a perforated domain. On the boundary of the perforations, we set either homogeneous Dirichlet o…
Generalized incompressible flows, multi-marginal transport and Sinkhorn algorithm
Jean-David Benamou, Guillaume Carlier, Luca Nenna
Starting from Brenier's relaxed formulation of the incompressible Euler equation in terms of geodesics in the group of measure-preserving diffeomorphisms, we propose a numerical me…
