The sudden transition of a trajectory from one basin of attraction to another.
In terms of H. and L. SABELLI: “Catastrophes are the simplest forms of bifurcations, i.e. the transition from one point attractor to another (i.e. choice or rejection). The simplest catastrophes are governed by only two control variables: a) asymmetric, which at mid values is associated with large changes between the opposite modes, while at extreme values is associated with small changes around the modes; and b) bifurcating, which at low values is associated with continuous outcomes and at high values, with a discontinuous outcome” (1992, p.663).
