Abstract
Based on the Bethe-Salpeter equation and the Ward identity derived from it, we provide a scheme for constructing the vertex function in the self-consi stent iteration loop to determine the electron self-energy. The scheme is i mplemented in the homogeneous electron gas at the sodium density.
