For original paper see J. Phys. C., vol.17, p.2537 (1984). Agarwal and co-workers have reported on dynamical properties of a classical two-dimensional, one-component homogeneous plasma with a logarithmic potential for an arbitrary Gamma = beta e². Some of their results may now be compared with those obtained analytically for Gamma =2. In addition, their phenomenological response function can be analysed with respect to the third moment and compressibility sum rules. This analysis indicates the extent of the validity of their response function.
