    • Diluted Ising systems without random fields will also exhibit logarithmic growth of domains when quenched into the ordered phase [, ]. However, in the critical region, the coherence will grow much more rapidly than in the random-field case (D. S. Fisher, unpublished).

    • formally calculate the dynamical exponent z in 6 - epsilon dimensions. The expected metastable configurations do not show up in their calculation for a subtle reason: In order to have several extrema of the effective Hamiltonian at a scale xi, it is necessary for the fixed-point Hamiltonian to have fluctuations in the local Tc of order 1. Since in 6 - epsilon dimensions the rms fluctuations are of order epsilon, rare (probably exponentially rare) fluctuations are necessary to yield metastable configurations on scale xi, although there will always be metastability on sufficiently long scales. [For a discussion of related problems see, 31, 1396, and to be published.] Thus the coefficient of the singular dynamical behavior found here may well vanish exponentially as epsilon -> 0+., D. S.

    • These authors also perform a schematic 2 + epsilon expansion which is, as expected, found not to satisfy dimensional reduction.
