Abstract: (Elsevier)
Low-energy properties of the lattice gauge theories U( N ) or SU( N ) with fermions are derived in the infinite-coupling limit from a 1 d expansion of Green's functions. Spontaneous global symmetry breaking is shown to occur. The analytically computed meson spectrum nearly coincides with the one obtained by Monte Carlo methods at finite coupling. Estimates of the baryon mass and pion decay constant are also given.
