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.
