The Maxwell equations on full sub-extremal and extremal Kerr spacetimes
Gabriele Benomio, Rita Teixeira da Costa
We study the Cauchy problem for the Maxwell equations in the exterior region of Kerr black hole spacetimes. The equations are formulated for components of the Maxwell field relativ…

Elliptic curvature estimates for linearised gravitational perturbations of Kerr in the full sub-extremal range
Gabriele Benomio, Rita Teixeira da Costa
We consider the linearised vacuum Einstein equations around a Kerr exterior solution and present a scheme to prove elliptic -estimates for the linearised curvatu…

On turbulence for spacetimes with stable trapping
Gabriele Benomio, Alejandro Cárdenas-Avendaño, Frans Pretorius +1
Motivated by understanding the nonlinear gravitational dynamics of spacetimes admitting stably trapped null geodesics, such as ultracompact objects and black string solutions to ge…
