Properties of some three-state, steady-state Ising systems, according to the Bragg-Williams approximation.
We consider the steady-state properties of a lattice of three-state, cycling enzyme molecules, with nearest-neighbor interactions treated by the Bragg-Williams (mean field) approximation. Only a few particular cases are examined, but these illustrate the rich phase-transition possibilities of this class of systems. "Bifurcation" cases were treated in a previous paper; the present examples are of the nonbifurcation type. However, a few new theoretical properties of bifurcation cases are included.
