(relativity)

Another was the extension of the invariance principle to accelerating observers: the laws of nature themselves should be identical for all observers, regardless of the magnitude or direction of their acceleration.
It follows from LaSalle invariance principle [15] that the infection-free equilibrium [E.

For time-invariant dynamical systems the invariance principle can be used to relax the strict negative-definiteness condition on the Lyapunov derivative.

In the cognitive blending model, the invariance principle, constraining the integration network against image-schematic clash in its required inputs and outcomes, apparently specifies at least one mandatory aspect or element of blending: image-schemata.
