Abstract Title: * Deformationless advection Authors: * Krasimira Yankova Institution: * Space Research and Technologies Institute - BAS Preferred format: * poster presentation Abstract Text: * In this paper consider the magneto-hydrodynamics on the system 'disk – corona' around the central black hole. Is analyzes the impact of the restructuring in the stream, over self-induction of the advection and exchange of energy. Shows post-Newtonian develop of the advective mechanism and approach to the upgrade of the model in GR. We will discuss behaviour on the emerging connections on the disk to the other components of quasars.
