Description

The Ward identity, relating the three-legged vertex function to the Green function, is derived for the one-dimensional normal many-fermion system making use of the equation of motion for the vertex function as well as by means of the gauge invariance of the system. The interaction of the system is taken either as a forward scattering or as a backward scattering. In the latter case only one momentum transfer is allowed. (author)
