We investigate stability of the scale-invariant solutions of the BBGKYequations for two-point spatial correlation functions of the densityfluctuations in the strongly non-linear regime. In the case that the backgroundskewness of the velocity field is equal to 0, we found that there is no localinstability in the strongly non-linear regime. The perturbation does not grownor does it decay. It has an only marginal stable mode. This result means thatno special value of the power index of the two-point spatial correlationfunction are favored in terms of the stability of the solutions. In otherwords, the argument about the stability does not determine the power index ofthe two-point spatial correlation functions in the strongly non-linear regime.Comment: 16 pages, no figures, uses aaspp4.sty, Submitted to Ap
