چکیده

In this paper we study the effects of noncommutative phase space deformations on the Schwarzschild black hole. This idea has been previously studied in Friedmann–Robertson–Walker (FRW) cosmology, where this “noncommutativity” provides a simple mechanism that can explain the origin of the cosmological constant. In this paper, we obtain the same relationship between the cosmological constant and the deformation parameter that appears in deformed phase space cosmology, but in the context of the deformed phase space black holes. This was achieved by comparing the entropy of the deformed Schwarzschild black hole with the entropy of the Schwarzschild–de Sitter black hole.

The phase transition of corrected black hole with f(R) gravity

In this letter, we consider static black hole in f(R) gravity.We take advantage from corrected entropy and temperature and investigate such black hole. Finally, we study the $ P - V $ critically and phase transition of corrected black hole with respect to entropy and temperature. Here also, we obtain the heat capacity for the static black hole in $ f(R) $ gravity. This calculation help us...

Thermodynamics of Regular Cosmological Black Holes with the de Sitter Interior

We address the question of thermodynamics of regular cosmological spherically symmetric black holes with the de Sitter center. Space-time is asymptotically de Sitter as r → 0 and as r → ∞. A source term in the Einstein equations connects smoothly two de Sitter vacua with different values of cosmological constant: 8πGT μ ν = Λδ ν as r → 0, 8πGT μ ν = λδ μ ν as r → ∞ with λ < Λ. It represents an ...

Topological Black Holes in Anti-de Sitter Space

A class of black hole solutions to Einstein’s equations in d dimensions with a negative cosmological constant is constructed. These solutions have the property that the horizon is a (d− 2)-dimensional manifold of constant curvature, but this curvature may be positive, zero, or negative. Asymptotically, the solutions are locally isometric to anti-de Sitter space. The mass, temperature, and entro...

Upper bound for entropy in asymptotically de Sitter space-time

We investigate nature of asymptotically de Sitter space-times containing a black hole. We show that if the matter fields satisfy the dominant energy condition and the cosmic censorship holds in the considering space-time, the area of the cosmological event horizon for an observer approaching a future timelike infinity does not decrease, i.e. the second law is satisfied. We also show under the s...

Action and entropy of black holes in spacetimes with cosmological constant

In the Euclidean path integral approach, we calculate the actions and the entropies for the Reissner-Nordström-de Sitter solutions. When the temperatures of black hole and cosmological horizons are equal, the entropy is the sum of one-quarter areas of black hole and cosmological horizons; when the inner and outer black hole horizons coincide, the entropy is only one-quarter area of cosmological...
