In [1] the equation for the temperature given in equation (3.4) is incorrect. When the

series in equation (2.17) is correctly summed using the choice for αj’s in equation (3.2) the

correct expression for the temperature is

T =~

8π(

M + α1~M4(~+M2)

) . (1)

For the choice of α1 = ±12 made in the paper this temperature is divergent as M → 0 rather

than convergent as claimed in the paper. The main results of [1] – the fact that higher

order quantum corrections do not change the thermal nature of the Hawking radiation, the

expression for the entropy given in (3.3) and the use of this entropy expression to explain

the information loss paradox — are not altered by the change in the expression for the

temperature. We also note that it is possible to choose α1 so as to have a finite temperature

as M → 0. The choice α1 = K~/M2 — where K is a dimensionless constant — gives a

T which is everywhere finite. The entropy for this choice of α1 still leads to an entropy

which is of the form M2 + Log[f(M)] where f(M) is some function of M . This form still

solves the information loss puzzle but for the choice of α1 given above the entropy is now

divergent as M → 0.

Acknowledgments

The authors would like to thank Dr. Izzet Sakalli for pointing out the mistake in the

expression for the temperature in the original article.
