✦ Synopsis

Plasma dispersion relations of art electron gas on a tubule are obtained in the random phase approximation and the one dimensional limit. Intraband plasmon has a relationship between the plasma frequency wp and the wavevector q of wp --~ q(]ln Rq/21) 112, and the interband plasmon has a relationship wp ,,~ const, in the long wave length limit.

Plasmon damping in the three-dimensional homogeneous electron gas is investigated within the formalism of secondorder perturbation theory, concentrating on the effects of static and dynamic screening. We have found several different theoretical approaches leading to comparable results, especially in
