Abstract
The dimensionless deforming parameter of the generalized uncertainty principle is computed from the generalized metric of a curved spacetime. We assume a deformation of the classical metric of General Relativity due to the quantum gravity corrections in order to compute the perturbed Hawking temperature and determine the deformation parameter of the generalized uncertainty principle. A non numerical value is obtained for the deformation parameter that is compared with the previously obtained values and bounds.
期刊介绍：
Annals of Physics presents original work in all areas of basic theoretic physics research. Ideas are developed and fully explored, and thorough treatment is given to first principles and ultimate applications. Annals of Physics emphasizes clarity and intelligibility in the articles it publishes, thus making them as accessible as possible. Readers familiar with recent developments in the field are provided with sufficient detail and background to follow the arguments and understand their significance.
The Editors of the journal cover all fields of theoretical physics. Articles published in the journal are typically longer than 20 pages.
