Scalar quasinormal and quasibound states of weakly magnetized Ernst--Schwarzschild spacetime: a confluent-Heun Wronskian approach

Danilo S. Ferreira, Luis B. Castro

We study the quasinormal-mode and quasibound-state spectra of a massless scalar field in weakly magnetized Ernst--Schwarzschild spacetime. In the separated $O (B_{0}^{2})$ regime, the K…

D. Ferreira, E. A. Lima, F. J. Palomo +1

A natural one codimension isometric embedding of each $(n + 1)$ -dimensional spherical Robertson-Walker (RW) spacetime $I \times_{f} S^{n}$ in $(n + 2)$ -dimensional Lorentz-Minkowsk…

Complete stationary spacelike surfaces in an $n$ -dimensional Generalized Robertson-Walker spacetime

Danilo Ferreira, Eraldo A. Lima, Alfonso Romero

Several uniqueness results for non-compact complete stationary spacelike surfaces in an $n (\geq 3)$ -dimensional Generalized Robertson Walker spacetime are obtained. In order to do…
