Abstract

F. Gesmundo and F. Viani have modeled the growth rates of two-oxide scales by the system: [formula omitted]. We provide a complete qualitative analysis of (1.1) by making use of known results about the general n-dimensional dynamical system: [formula omitted]. We show that for m > 1, the Gesmundo-Viani system admits a unique parabolic solution. [formula omitted]. This parabolic solution attracts all other solutions. Every solution extends uniquely to a solution on [0, +oo), such that the extended solution is eventually monotonically increasing. Finally, the trajectory of any solution coincides with a trajectory of the following linear system: [formula omitted]
