marked differences we first express these contraint equations, which have an
“external potential” form similar to coupled one-body Dirac equations, in a
hyperbolic form. These coupled equations are then re-cast into two equiv-
alent equations: (1) a covariant Breit-like equation with potentials that are
exponential functions of certain “generator” functions, and (2) a covariant or-
thogonality constraint on the relative momentum. This reduction enables us
to show in a transparent way that finite-r singularities do not a
