Query: Interrelation of a Z(3) Gauge Theory on the Flat Lattices and a Spin-1
  BEG Model   The Z(3) gauge model with double plaquette representation of the action on
the flat triangular and square lattices is constructed. It is reduced to the
spin-1 Blume-Emery-Griffiths (BEG) model. An Ising-type critical line of a
second-order phase transition is found.
