    • In this paper (except in Appendix B) we consider f as the distribution function in the velocity space alone, i.e., the commonly used f normalized by the density ρ.

    • The same result can be obtained directly from the “test particle equation”10 by multiplying it by [formula omitted] and integrating over Ï…. This procedure results in an equation of motion for the granular temperature with an energy sink term identical to the one given in Eq. (36).

    • The regression slope is based on all points in the case of [formula omitted] and on the first four points in the case of [formula omitted] i.e., before the “inelastic collapse” sets in.

    • Notice that if we had taken [formula omitted] in the three-particle distribution function then the average given in Eq. (80) would have vanished.

    • The reason that the simulated critical value of e is somewhat lower than the one predicted by Eq. (62), may be attributed to the fact that the Gaussian distribution is not a solution of the homogeneous Boltzmann equation. The latter should evolve to a two-hump distribution (cf. Fig. 3). As the instability (discussed in this paper) evolves so does the distribution function. Considering the fact that an approximate flat distribution is a transient stage in the development of the distribution function from its Gaussian shape to two-hump form, it is clear that the exact critical value of e should be between that predicted by using the Gaussian distribution and the one predicted by employing the flat distribution.
