The Universe

We study the corrections to the fine structure constant from the generalized uncertainty principle in the spacetime of a domain wall. We also calculate the corrections to the standard formula to the energy of the electron in the hydrogen atom to the ground state, in the case of spacetime of a domain wall and generalized uncertainty principle. The results generalize the cases known in literature.

Global Monopole

In this paper we use the Generalized Uncertainty Principle in order to obtain the corrections to the fine structure constant in (D + 1)-dimensional global monopole spacetime. We also discuss the case D = 3 corresponding to the (3+1)-dimensional global monopole spacetime.
