摘要：

A modified Feynman construction with a zero-frequency central peak is used to model the dynamical structure functions for layered charged particle systems. This construction recognizes the affinity between layered and multicomponent systems. It also guarantees the simultaneous satisfaction of all three frequency-moment sum rules. The frequencies and spectral weights of the long-wavelength collective excitations and the strength of the diffusive central peak are calculated for arbitrary degeneracy.
