On the thermal stability of a static spherically symmetric black holes in Nash embedding framework
Abraão J. S Capistrano, Antonio C. Gutiérrez-Piñeres, Sergio C. Ulhoa +1
We study the deformation caused by the influence of extrinsic curvature on a vacuum spherically symmetric metric embedded in a five-dimensional bulk. In this sense, we investigate…
Symplectic Dirac Equation
R. G. G. Amorim, S. C. Ulhoa, Edilberto O. Silva
Symplectic unitary representations for the Poincaré group are studied. The formalism is based on the noncommutative structure of the star-product, and using group theory approach a…
Black Holes Thermodynamics in a new kind of Noncommutative Geometry
Mir Faizal, R. G. G. Amorim, S. C. Ulhoa
Motivated by the energy dependent metric in gravity's rainbow, we will propose a new kind of energy dependent noncommutative geometry. It will be demonstrated that like gravity's r…
On Non-Commutative Correction of the Gödel-type Metric
S. C. Ulhoa, A. F. Santos, R. G. G. Amorim
In this paper, we will study non-commutative corrections in the metric tensor for the Gödel-type universe, a model that has as its main characteristic the possibility of violation…
