<hidden TTP05-05  Energy-square equations for relativistic closed systems. > The most powerful relativistic two-body equations
 have only half as many components as their Dirac-Breit and
 Bethe-Salpeter counterparts and contain only the square of the total
 cms energy. In this letter, the "energy-square" theorem is extended to
 systems of $n>2$ Dirac particles. The case $n=3$ is discussed for baryons.
