✦ Synopsis

The electronic scattering Green function formalism is applied to a system processing a n-lold symmetry axis. A suitable discretization of the Lippmann-Schwinger equations leads to the inversion of block circuhmt matrices. This calcu[afiou is carried out by using a specialized algorithm, also described, which fully exploits the formal consequences of symmetD'.
