Phase diagram for system (1). The curves (1), (2) are spinodal and binodal, respectively [for changing from 0 to 0.4 they are trivial ones, for , curve , nontrivial spinodal], is the critical point (marked by 엯), is the Lifshitz point (marked by ×).
The spatial distribution for for the system (1) bold curve, for ; next curve, for and value , corresponding to binodal; dotted line, for . The curves are plotted in the scale .
Phase diagram for system (2). The curve (1), trivial spinodal, the curve (2) is nontrivial spinodal, (3) is the trivial binodal, is the Lifshitz point (marked by ×), is the critical point (marked by 엯).
The bifurcation diagram for the system (2) at . The curve (1) is the unstable nonhomogenous branch, (2) is the stable one, (3) the stable part of the branch appeared transcritically from the spinodal point, (4) is the unstable part of the same branch, (5) is the stable homogeneous nontrivial branch rigidly arising in couple with branch (4).
The bifurcation diagram at for the system (3).
