Abstract
We extend the treatment of translation symmetry, which is usually limited to orbitals (one-electron functions), to many-electron functions. The distinction between translational invariance and translation symmetry is analysed. We define an explicit translation operator for many-electron functions. The many-electron translation operators are related to the many-electron momentum operator, of which several forms are discussed.
