Migdal’s recursion equation proposed for the Wilson lattice gauge theory is studied for its weak and strong coupling behavior. The model is then solved numerically for the SU(2) gauge field, and it is shown that there is a continuous crossover from the weak coupling (asymp-totically free) region to the strong coupling (quark confining) domain. The Migdal recursion equation is a crude approximation for the behavior of the gauge field in d=4 dimension, and provides a theo-retical example of how confinement of quarks could be achieved by the gauge field which exhibits asymptotic freedom
