Abstract
The dynamical group associated with the Dirac equation with a radially symmetric potential in four space-time dimensions is represented in terms of integrals with respect to operator valued set functions associated with the free Dirac operator. In coordinates in which c = ℏ = 1, the class of potentials treated includes Coulomb potentials —a/r with |a| < 1.
