چکیده
Noncommutative geometry is an established potential candidate for including quantum phenomena in gravitation. We outline the formalism of Hopf algebras and its connection to algebra infinitesimal diffeomorphisms. Using a Drinfeld twist we deform spacetime symmetries, vector fields differential forms leading formulation noncommutative Einstein equations. study concrete example charged BTZ deformations steaming from so called angular twist. The entropy black hole obtained using brick-wall method. used scalar field as probe spectrum density states via WKB approximation. provide method calculate corrections Bekenstein-Hawking higher orders WKB, but present final result lowest order. that even order entropy, general, contains powers $\hbar$, it has logarithmic corrections, polynomials logarithms area.

Noncommutative BTZ Black Hole and Discrete Time
We search for all Poisson brackets for the BTZ black hole which are consistent with the geometry of the commutative solution and are of lowest order in the embedding coordinates. For arbitrary values for the angular momentum we obtain two two-parameter families of contact structures. We obtain the symplectic leaves, which characterize the irreducible representations of the noncommutative theory...
متن کاملLogarithmic correction to the Bekenstein-Hawking entropy of the BTZ black hole
We derive an exact expression for the partition function of the Euclidean BTZ black hole. Using this, we show that for a black hole with large horizon area, the correction to the Bekenstein-Hawking entropy is −3/2 log(area), in agreement with that for the Schwarzschild black hole obtained in the four dimensional canonical gravity formalism and also in a Lorentzian computation of BTZ black hole ...

متن کاملCanonical entropy of three-dimensional BTZ black hole
Recently, Hawking radiation of the black hole has been studied using the tunnel effect method. It is found that the radiation spectrum of the black hole is not a strictly pure thermal spectrum. How does the departure from pure thermal spectrum affect the entropy? This is a very interesting problem. In this paper, we calculate the partition function by energy spectrum obtained from tunnel effect...
متن کاملWhat We Don’t Know about BTZ Black Hole Entropy
With the recent discovery that many aspects of black hole thermodynamics can be effectively reduced to problems in three spacetime dimensions, it has become increasingly important to understand the “statistical mechanics” of the (2+1)-dimensional black hole of Bañados, Teitelboim, and Zanelli (BTZ). Several conformal field theoretic derivations of the BTZ entropy exist, but none is completely s...
