Journal ArticleDOI
H-functions and mixing in violent relaxation
TL;DR: In this paper, a critere simple permettant de determiner si une fonction de distribution donnee est plus melangee qu'une autre is used for determining whether l'etat initial est froid or a grumeaux.
Journal ArticleDOI
Reconstruction of the early Universe as a convex optimization problem
Yann Brenier,Uriel Frisch,Uriel Frisch,Michel Hénon,Grégoire Loeper,Sabino Matarrese,Roya Mohayaee,A. Sobolevskiĭ +7 more
TL;DR: In this article, it was shown that the deterministic past history of the universe can be uniquely reconstructed from knowledge of the present mass density field, the latter being inferred from the three-dimensional distribution of luminous matter, assumed to be tracing the distribution of dark matter up to a known bias.

TL;DR: In this article, the authors show that the past history of the universe can be uniquely reconstructed from the knowledge of the present mass density field, the latter being inferred from the 3D distribution of luminous matter, assumed to be tracing the distribution of dark matter up to a known bias.
Journal ArticleDOI
A simple model of Saturn's rings
TL;DR: The distribution of particle sizes in Saturn's rings is probably continuous over many orders of magnitude; there is no "typical particle size" as mentioned in this paper, and a model based on this view accounts for observed properties of the rings: apparent thickness, radar and radio observations, number and size distribution of the gaps discovered by Voyager 1, and optical thickness.
Journal ArticleDOI
Low-viscosity lattice gases
TL;DR: In this paper, three-dimensional lattice gas models with very low (and possibly negative) viscosities have been studied theoretically and tested in numerical implementations, and they have been shown to work well in numerical simulations.
