چکیده
In this paper, we consider $(n+1)$-dimensional topological dilaton de Sitter black holes with power-Maxwell field as thermodynamic systems. The quantities corresponding to the hole horizon and cosmological respectively are interrelated. So total entropy of space-time should be sum entropies plus a corrected term which is produced by association two horizons. We analyze entropic force at given temperatures, affected parameters dimensions space-time. It shown that change position ratio horizons in some region similar Lennard-Jones particles. If effect force, other forces absent, motion relative would have an oscillating process. between probably one participants drive evolution universe.

Dilaton black holes with squashed horizons and their thermodynamics
New charged solutions describing black holes with squashed horizons in 5D dilaton gravity are presented. The black hole spacetimes are asymptotically locally flat and have a spacial infinity R× S →֒ S. The solutions are analyzed and their thermodynamics is discussed by using the counterterm method.
متن کاملBlack holes with regular horizons in Maxwell - scalar gravity .
A class of exact static spherically symmetric solutions of the Einstein-Maxwell gravity coupled to a massless scalar field has been obtained in harmonic coordinates of the Minkowski space-time. For each value of the coupling constant a, these solutions are characterized by a set of three parameters, the physical mass μ0, the electric charge Q0 and the scalar field parameter k. We have found tha...
متن کاملTwo-Dimensional Dilaton Black Holes
The two-dimensional CGHS model provides an interesting toymodel for the study of black hole evaporation. For this model, a quantum effective action, which incorporates Hawking radiation and backreaction, can be explicitly constructed. In this paper, we study a generalization of this effective action. In our extended model, it is possible to remove certain curvature singularities arising for the...
متن کاملOn uniqueness of static Einstein-Maxwell-dilaton black holes
We prove uniqueness of static, asymptotically flat spacetimes with nondegenerate black holes for three special cases of Einstein-Maxwell-dilaton theory: For the coupling “α = 1” (which is the low energy limit of string theory) on the one hand, and for vanishing magnetic or vanishing electric field (but arbitrary coupling) on the other hand. Our work generalizes in a natural, but non-trivial way...
متن کاملBlack Holes and Two - Dimensional Dilaton Gravity
We study the conditions for 2-dimensional dilaton gravity models to have dynamical formation of black holes and construct all such models. Furthermore we present a parametric representation of the general solutions of the black holes.
