摘要：

The dielectric response function chi of a uniform electron gas is investigated up to the second order of the Coloumb interaction with different methods. When examining all polarization diagrams with two interaction lines, it is confirmed that previous work in the Green's function formalism does not contain all second order processes and the importance of the corrections is pointed out. It is further shown how the evaluation of chi with Green's function can be greatly simplified when taking into account the symmetry of the expressions.
