a point to which a system tends to return following some perturbation; a given system may have multiple equilibrium points.
The price at which the quantity supplied by sellers equates to the quantity demanded by buyers.
A point which is invariant under the flow for a given dynamical system. It is the graph of a constant solution. One finds equilibrium points by finding where the right hand sides of the given system of differential equations are all zero, i.e. where there is no change in the dependent variables.
This word is often interchangeably used with the term fixed point. These points are found by finding the point(s) that satisfy f(x)=0 from the state space equation x'=f(x). In a physical context, stable equilibria are those solutions to f(x)=0 which are obtainable in an experimental setting.
The point in a market where the demand for a product and the supply of that product are exactly equal. If supply were greater, the price would fall. If demand were greater, the price would rise. Free markets tend to move toward their equilibrium point.
In mathematics, the point \tilde \mathbf{x}\in \mathbb{R}^n is an equilibrium point for the differential equation
