In mathematics, specifically in differential equations, an equilibrium point is a constant solution to a differential equation.
The point x~∈Rn{\displaystyle {\tilde {\mathbf {x} }}\in \mathbb {R} ^{n}} is an equilibrium point for the differential equation
if f(t,x~)=0{\displaystyle \mathbf {f} (t,{\tilde {\mathbf {x} }})=0} for all t{\displaystyle t\,\!}.
