Generalized uncertainty principle, modified dispersion relation and Reissner–Nordström black hole tunneling radiation

The Parikh–Kraus–Wilczek tunneling proposal of black hole tunneling radiation is considered. Reissner–Nordström black hole thermodynamics is studied according to the generalized uncertainty principle and the modified dispersion relation analysis. It is shown that entropy, temperature and the original Parikh–Kraus–Wilczek calculation of the black hole tunneling probability receive new corrections. The results of these two alternative approaches are identical if one uses the suitable expansion coefficients.
