Accretion of perfect fluids onto a class of regular black holes
Juliano C. S. Neves, Alberto Saa
We consider the stationary spherical accretion process of perfect fluids onto a class of spherically symmetric regular black holes corresponding to quantum-corrected Schwarzschild…
Optimal global synchronization of partially forced Kuramoto oscillators
Joyce S. Climaco, Alberto Saa
We consider the problem of global synchronization in a large random network of Kuramoto oscillators where some of them are subject to an external periodically driven force. We expl…
Dynamical equivalence of gravity in Jordan and Einstein frames
Saikat Chakraborty, Sanchari Pal, Alberto Saa
We investigate the dynamics of gravity in Jordan and Einstein frames. First, we perform a phase-space singularities analysis in both frames. We show that, typically, anisotr…
Huygens' envelope principle in Finsler spaces and analogue gravity
Hengameh R. Dehkordi, Alberto Saa
We extend to the -dimensional case a recent theorem establishing the validity of the Huygens' envelope principle for wavefronts in Finsler spaces. Our results have direct applic…
