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.
在动力学系统中,多重稳定性是在矢量空间中具有多个稳定的平衡点的特性,该平衡点由系统中的状态跨越。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。 与前三个拉格朗日点一样,在某些维度上稳定而在其他维度上不稳定的点被称为不稳定点。
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。这是多重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来分隔两个点。
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,
which can cause it to develop in one of multiple divergent directions.
这导致它向多个不同的方向中的一个发展。
In economics and social sciences, path dependence gives rise to divergent directions of development.
在经济学和社会科学中,路径依赖引起了发展方向的分歧。
Some path dependent processes are adequately described by multistability,
多重稳定性充分描述了一些路径的依赖过程,
by being initially sensitive to input, before reaching a stagnant state –
在进入停滞状态之前,最初对输入很敏感
for example market share instability, which can develop into a stable monopoly for one of multiple possible vendors.
例如,市场份额的不稳定,可能会演变成多个可能的供应商之一的稳定垄断。
Multistable perception
Ambiguous images
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模式,如内克魔方、单眼竞争或双眼竞争,而引起的摇摆感知。
Through lateral inhibition, a pattern in which one image, when stimulated, inhibit the activity of neighboring images.
通过横向抑制,其中一个图像在受到刺激时会抑制邻近图像的活动。
