V originále
Humpy LNRF-velocity profiles were found for both Keplerian thin discs and marginally stable thick discs orbiting nearly extreme Kerr black holes, being located just above the innermost stable circular orbit. The global character of this phenomenon is given by topology changes of equivelocity (von Zeipel) surfaces in marginally stable discs, as the standard cylindrical von Zeipel surfaces are transformed into toroidal surfaces existing around the circle corresponding to the local minimum of the equatorial humpy LNRF velocity profile.
