Query: Logarithmic Correlations in Quenched Random Magnets and Polymers   It is argued that logarithmic factors multiplying power law behavior are to
be expected at or near non-mean field critical points of systems with
short-range interactions described theoretically by any kind of n -> 0 limit,
in which the effective free energy vanishes. Explicit examples are given for
quenched random ferromagnets, polymer statistics and percolation, but the
phenomenon is quite general.
