“…Third, the features of the solutions to the model are studied using the concepts of dynamic systems theory, for example, those of stability or attractors. Here and in what follows, a model is simply a set of equations that have an interpretation in terms of a real-world target system (other types of models, e.g., models that do not aim at representing real-world targets or that are not naturally thought of as sets of equations, do not matter for our purposes; see Chuang, Bell, Banke, &Baayen, 2021, andFrank, 2021, in this volume for modeling approaches to multilingualism).…”
