Numerical Study of the Gluon Propagator in Lattice Landau Gauge: the   Three-Dimensional Case
  We study the infrared behavior of the gluon propagator in lattice Landau gauge, for pure SU(2) lattice gauge theory in a three-dimensional lattice. Simulations are done for nine different values of the coupling $\beta$, from $\beta = 0$ (strong coupling) to $\beta = 6.0$ (in the weak-coupling region). In the limit of large lattice volumes, we observe in all cases a gluon propagator decreasing as the momentum goes to zero.
