LeanPool.NavierStokesAndEuler.Euler.EnergyForcingIdentity

Exact identification of the limiting actual metric forcing with the seven spatial correction terms.

The actual H¹→L² transport depends only on the underlying velocity field, independently of its Sobolev order.

The literal metric transport of a concatenated energy word is exactly the top transport in the spatial telescope.

Negating a genuine Sobolev field negates every exact external/base energy word.
