Chaotic motion of particles around a dyonic Kerr-Newman black hole immersed in the Melvin-swirling universe
Deshui Cao, Lina Zhang, Songbai Chen +2
We employ the Poincaré section, fast Lyapunov indicator, recurrence analysis, bifurcation diagram and basins of attraction to investigate the dynamical behaviors of the motion of…

Chaotic motion of particles in the spacetime of a Kerr black hole immersed in swirling universes
Deshui Cao, Lina Zhang, Songbai Chen +2
We investigate the motion of particles in the spacetime of a Kerr black hole immersed in swirling universes. Using the Poincaré section, fast Lyapunov exponent indicator, bifurcat…
