Comment on the ``Invariance of the Tunneling Method for Dynamical Black Holes''

Abstract

In the recent paper arXiv:0906.1725 it has been guessed that a ``correct'' treatment of the semi-classical tunneling based on the Hamilton-Jacobi equation gives the standard Hawking formula, contrary to was asserted in my previous paper arXiv:0904.4572. Here I confirm my calculation showing where the article of Di Criscienzo et al. is wrong.
