摘      要：We have studied the effect of the third-order density fluctuations in the medium on the collective excitations in quark-gluon *** show that the nonlinear response of a quark-gluon plasma medium leads to non-Abelian collective *** present two kinds of non-Abelian oscillation solutions which respectively correspond to weakly and strongly nonlinear coupling of field components in the color *** also show that the weakly nonlinear solution is similar to the Abelian-like one but has a frequency shift,which is of order g^(2)T,from the eigenfrequency.
