On Quantum Gravity of Space-Time with Horizon

In the present work the high-energy deformation at Planck’s scale for space-time with horizon is suggested on condition that the Generalized Uncertainty Principle is fulfilled. The deformation is understood as an extension of a particular theory by inclusion of one or several additional parameters in such a way that the initial theory appears in the limiting transition. In the beginning, this deformation is considered for black holes with Schwarzschild’s metric. Then the obtained results are generalized for the De Sitter space and black holes with Schwarzschild-De Sitter Metrics. In the concluding section, the problems for further studies are put forward and the applications of the results are shown.
