The isospectrality of asymptotic quasinormal modes of large Gauss-Bonnet d-dimensional black holes
Filipe Moura, João Rodrigues
We compute the quasinormal frequencies of d-dimensional large spherically symmetric black holes with Gauss-Bonnet corrections in the highly damped regime. We solve perturbatively t…
Primordial magnetic fields in theories of gravity with non-minimal coupling between curvature and matter
Orfeu Bertolami, Maria Margarida Lima, Filipe C. Mena
The existence of magnetic fields in the universe is unmistakable. They are observed at all scales from stars to galaxy clusters. However, the origin of these fields remains enigmat…
Quasinormal modes and stability of boosted Reissner-Nordström AdS black holes
Rodrigo D. B. Fontana, Filipe C. Mena
We investigate the numerical stability of accelerated AdS black holes against linear scalar perturbations. In particular, we study the evolution of a probe non-minimally coupled sc…
Higher Vector Bundles
Matias del Hoyo, Giorgio Trentinaglia
We introduce higher analogs for cleavages in the context of (Kan) simplicial fibrations. We apply them to obtain geometric models for representations up to homotopy of (higher) Lie…
An abstract theory of physical measurements
Pedro Resende
The question of what should be meant by a measurement is tackled from a mathematical perspective whose physical interpretation is that a measurement is a fundamental process via wh…
