A study of the stability of classical systems under the influence of t
wo conflicting single-well, single-variable potentials is presented. T
he control parameters are a so-called conflict parameter c, the distan
ce between the two conflicting attractors, and an asymmetry parameter
a which determines the relative strength of the two attractors. For co
nvex potentials, the influence of conflict on the system stability dep
ends on the sign of the third derivative of the conflicting potential
functions, resulting in two categories called U-and V-type potentials.
The introduction of a concave branch (bias) in convex conflicting pot
entials qualitatively changes the system behavior, by generating bifur
cation and discontinuity. The cusp catastrophe can be redefined as the
conflict between two such biased single-well potentials. The main int
erest of the new representation potentially lies in the evocative powe
r of the control parameters a and c. The mapping of(a,c) on (u,v), the
traditional control parameters of the cusp catastrophe, is given. The
cusp develops above a certain critical value of the conflict paramete
r c.
