Abstract/Résumé:

We prove that there exists a phase space of canonical variables, for the initial value problem for axially symmetric Maxwell fields with compactly supported initial data and propagating in Kerr-de Sitter black hole spacetimes, such that their motion is restricted to the level sets of a positive-definite Hamiltonian, despite the ergo-region.

On démontre qu’il existe un espace de phase de variables canoniques, pour le problème des valeurs initials pour les champs de Maxwell symétriques à donneés initiales de support compact et à propagation dans les espaces-temps de trou noir Kerr-de Sitter, tel que leur motion est restrainte aux ensembles de niveau d’une hamiltonienne de type positif, en dépit de l’ergo-région.
