Query: Logarithmic Corrections to Black Hole Entropy from the Cardy Formula   Many recent attempts to calculate black hole entropy from first principles
rely on conformal field theory techniques. By examining the logarithmic
corrections to the Cardy formula, I compute the first-order quantum correction
to the Bekenstein-Hawking entropy in several models, including those based on
asymptotic symmetries, horizon symmetries, and certain string theories. Despite
very different physical assumptions, these models all give a correction
proportional to the logarithm of the horizon size, and agree qualitatively with
recent results from ``quantum geometry'' in 3+1 dimensions. There are some
indications that even the coefficient of the correction may be universal, up to
differences that depend on the treatment of angular momentum and conserved
charges.
