摘要
We find in the brick wall model that the entropy of scalar matter in an extremal Reissner-Nordstrom background does not vanish and in fact has a stronger divergence than usual. We also interpret earlier results on the classical action of these black holes to argue that the mass may be a measure of the gravitational entropy, somewhat like in string models.
