In a dynamical system, multistability is the property of having multiple stable equilibrium points in the vector space spanned by the states in the system. By mathematical necessity, there must also be unstable equilibrium points between the stable points. Points that are stable in some dimensions and unstable in others are termed unstable, as is the case with the first three Lagrangian points.

在动力系统系统中,多稳定性是系统状态跨越向量空间中多个稳定平衡点的性质。根据数学上的必然性,在稳定点之间也一定存在不稳定的平衡点。在某些维度上稳定而在另一些维度上不稳定的点被称为不稳定点,就像前三个拉格朗日点一样。


Bistability

Bistability is the special case with two stable equilibrium points. It is the simplest form of multistability, and can occur in systems with only one state variable, as it only takes a one-dimensional space to separate two points.

双稳态是具有两个稳定平衡点的特殊情形。这是多稳定性的最简单形式,可以发生在只有一个状态变量的系统中,因为它只需要一个一维空间就可以分离两个点。


Initial instability

Near an unstable equilibrium, any system will be sensitive to noise, initial conditions and system parameters,

在不稳定平衡点附近,任何系统对噪声、初始条件和系统参数都很敏感,

In economics and social sciences, path dependence gives rise to divergent directions of development.

在经济学和社会科学中,路径依赖导致了发展方向的分歧。

Some path dependent processes are adequately described by multistability,

例如,市场份额不稳定,这可能发展成为一个稳定的垄断多个可能的供应商之一。

模棱两可的图像

In vision science, multistable perception characterizes the wavering percepts that can be brought about by certain visually ambiguous pattern such as the Necker cube, monocular rivalry or binocular rivalry.

在视觉科学中,多稳态知觉描述了由于某些视觉上模糊的图案,如内克河立方体、单眼竞争或双眼竞争,而产生的摇摆感知。
