Abstract

It is argued that the recent prediction of the a dependence of the coupling, g(a), of an effective lattice gauge theory for quarkless quantum chromodynamics is confirmed by a recent numerical evaluation of g(a) for a latticized SU(2) gauge theory, thus providing strong evidence for the dynamical role of instantons. Additional predictions, testing the validity of the quantum chromodynamics bag model, are presented.
