Karazin popup.description2 The object under investigation is the event horizon of a black hole, its properties and properties of the processes in its vicinity. The basic methods of research include the analysis of the Einstein equations, the membrane approach, the quasiblack hole approach, the analysis of the behaviour of geodesic particles in the near-horizon region. The results obtained can be used in theoretical physics and astrophysics. We found the conditions under which equilibrium is possible between electrically charged matter and the event horizon. The conditions of the acceleration of particle by black holes are found. The properties of the entropy of black and quasiblackl holes are investigated. We showed that quasiblack hole approach enables to obtain the value of the entropy in the extremal case. It runts out that this value is nodal-dependent and depends also on the prehistory - how the (quasi)black Product Description popup.authors Заславський О. popup.nrat_date 2020-04-02 Close
