Abstract
In this chapter, we present a mathematical analysis of the dynamics of phase transitions with a non-conserved order parameter e (Model A phase transitions). In this connection, we refer to Section 4.4, where a mathematical model for such phase transitions has been developed that explains the possible occurrence of an accompanying hysteresis in the framework of Landau-Ginzburg theory. The approach of Section 4.4 led to
as the kinetic equation governing the evolution of the order parameter e, while the balance of internal energy was given by

This boundary condition has been discussed in Horn-Laurençot-Sprekels (1994). Kenmochi-Niezgodka (1993/94) use the condition For nonlinear boundary conditions, see Colli-Sprekels (1994, 1995b). Homogeneous Neumann conditions (i.e. β = 0) have been considered by Zheng (1992) in one space dimension. We may regard (3.4) as a linearized version of the correct boundary condition.

Indeed, it is easily verified that the nonlinear parabolic system (3.104)–(3.107) is triangular and normal parabolic, so that Theorem 5.2 in Amann (1989) yields that (e, T) is a global solution. We also refer to Amann (1993).
