On geodesic dynamics in deformed black-hole fields
Oldřich Semerák, Petra Suková
"Almost all" seems to be known about isolated stationary black holes in asymptotically flat space-times and about the behaviour of {\em test} matter and fields in their backgrounds…

Chaotic and stochastic processes in the accretion flows of the black hole X-ray binaries revealed by recurrence analysis
Petra Suková, Mikolaj Grzedzielski, Agnieszka Janiuk
The black hole candidates exhibit fast variability of their X-ray emission on a wide range of timescales. The short, coherent variations, with frequencies above 1 Hz, are referred…

Free motion around black holes with discs or rings: between integrability and chaos -- IV
V. Witzany, O. Semerak, P. Sukova
The dynamical system studied in previous papers of this series, namely a bound time-like geodesic motion in the exact static and axially symmetric space-time of an (originally) Sch…
