stable equilibrium

The condition of a structure in equilibrium; when a slight disturbance is applied to the structure and then removed, the structure returns to its equilibrium position. Compare with unstable equilibrium.

The higher solution corresponds to the stable equilibrium (solid curve); the smaller solution corresponds to the unstable equilibrium (dashed curve).
In Figure 1, the broken line A-D-B shows the boundary that it is not affected by external factors, indicating that there is a stable equilibrium solution, whether producer 1 selects cooperation or competition.

The coexistence of the stable equilibrium point and the limit cycle and the coexistence of the limit cycle and chaotic attractors both were common multistable phenomena in the supercavitating vehicle system.

A sufficiently strong disturbance, how ever, will put the system out of the metastable state, and the system will pass into a new state of stable equilibrium (Tschoegl, 2000).
As an aside, when the currency manager expressed his concern about the U.S.'s ostensible inability to have positive real rates over the next decade, a Fed policymaker said "this outlook is unrealistic as it wouldn't provide a stable equilibrium. My response: I never suggested this would be stable."
1) so, for m < [M.sub.max] there are two values for central density but only the lower value must be considered to describe stable neutron stars; the maximum mass is thus considered the maximum possible mass for a stable equilibrium configuration of neutron stars with a Fermi equation of state as obtained by Oppenheimer and Volkoff.
If the polynomial [alpha]([[absolute value of z].sup.2]) is not identically zero, then the origin is a stable equilibrium point.
