  In the Hamiltonian approach to Coulomb gauge Yang-Mills theory, the
functional Schroedinger equation is solved variationally resulting in a set of
coupled Dyson-Schwinger equations. These equations are solved self-consistently
in the subcritical regime defined by infrared finite form factors. It is shown
that the Dyson-Schwinger equation for the Coulomb form factor fails to have a
solution in the critical regime where all form factors have infrared divergent
power laws.
