Fine Structure Constant, Domain Walls, and Generalized Uncertainty
  Principle in 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.
