[4] Phase space is always the tangent fibre bundle of the manifold configuration space.
[5] Actually E is 6-dimensional if we bear in mind the constraint (2).
[6] Since μ is the tangent bundle of a metric manifold (i. e. U4), then on this space one can construct a canonical metric tensor GAB. See the article by Lindquist (Ref. [2]) and references quoted therein.
[7] By « effective volume » we mean a 6-dimensional volume. This conservation law, i. e. the Liouville theorem, means that if Δ1 ⊂ Σ1 is such a 6-dimensional volume, then mes (Δ1) = mes (Δ2) where Δ2 is the « volume » in Σ2 obtained from the transformation of Δ1 under the group motion (i. e. Eq. (3)).

and ,[9] This would be only a simple generalization of previous results where the electromagnetic radiation was dealt with (See Ref. [3] and also Relativistic kinetic equations including radiation effects I. Vlasov approximation (to appear in J. Math. Phys., 9, 116 (1968)). | Zbl

[15] In the same way as neglecting correlations of electromagnetic field or of particles amounts to dealing with a kinetic equation valid at order ∼ e2, neglecting correlations of the gravitational field is expected to provide a kinetic equation valid at order χ. We verify this statement on the resulting equation.
