The functional Schrodinger equation (FSE) for QCD gives a unique perspectiveon generation of a gluon mass m, as required for center vortices. The FSE,which yields a special d=3 gauge action, combined with lattice calculationsstrictly in d=3 give a value for the dimensionless ratio of d=3 coupling tomass g_3^2/m. From this we infer a reasonably accurate value for the d=4running coupling g^2(0) in the region of low momentum where it is nearlyconstant. The result, consistent with other estimates, is too low to drivechiral symmetry breaking (CSB) for quarks in a standard gap equation that hasno explicit confinement effects. We recall and improve on old work showing thatconfinement implies CSB for quarks, and consider CSB for test (that is,quenched) Dirac fermions in the adjoint representation. Here thepreviously-found value of $g^2(0)$ is large enough to drive CSB in a gapequation, which we relate to the presence of center vortices (non-confining,for the adjoint) and nexuses that drive fermionic zero modes. We discuss theextension of adjoint CSB to finite temperature.
