Two new discrete inequalities of Poincaré–Friedrichs on discontinuous spaces for Maxwell's equations
Abdelhamid Zaghdani, Christian Daveau · Comptes Rendus Mathématique · 2005
We present two new discrete inequalities of Poincaré–Friedrichs on discontinuous spaces for Maxwell's equations. The proofs of the inequalities are based on some decompositions formulas of L 2 ( Ω ) 3 .
