Asymptotically constant-free and polynomial-degree-robust a posteriori estimates for space discretizations of the wave equation
T. Chaumont-Frelet
We derive an equilibrated a posteriori error estimator for the space (semi) discretization of the scalar wave equation by finite elements. In the idealized setting where time discr…

A posteriori error estimates for finite element discretizations of time-harmonic Maxwell's equations coupled with a non-local hydrodynamic Drude model
T. Chaumont-Frelet, S. Lanteri, P. Vega
We consider finite element discretizations of Maxwell's equations coupled with a non-local hydrodynamic Drude model that accurately accounts for electron motions in metallic nanost…
