Quasinormal modes in generalized Nariai spacetimes

J Venâncio, C Batista - Physical Review D, 2018 - APS
The perturbations of fields with spin 0, 1/2, and 1 propagating in a higher-dimensional
generalization of the charged Nariai spacetime are investigated. The boundary conditions …

Two-component spinorial formalism using quaternions for six-dimensional spacetimes
