- n. The condition of being equivariant
Sorry, no etymologies found.
So it is with Bohmian mechanics, except that for the Bohmian system stationarity is not quite the right concept, and it is rather the notion of equivariance that is relevant.
Thus equivariance expresses the mutual compatibility, relative to ÏÏ, of the SchrÃ¶dinger evolution of the wave function and the Bohmian motion of the configuration.
