Relative information entropy and Weyl curvature of the inhomogeneous Universe
Nan Li, Thomas Buchert, Akio Hosoya +2
Penrose conjectured a connection between entropy and Weyl curvature of the Universe. This is plausible, as the almost homogeneous and isotropic Universe at the onset of structure f…

Lagrangian theory of structure formation in relativistic cosmology I: Lagrangian framework and definition of a nonperturbative approximation
Thomas Buchert, Matthias Ostermann
In this first paper we present a Lagrangian framework for the description of structure formation in general relativity, restricting attention to irrotational dust matter. As an app…

Relativistic cosmological perturbation scheme on a general background: scalar perturbations for irrotational dust
Xavier Roy, Thomas Buchert
In standard perturbation approaches and N-body simulations, inhomogeneities are described to evolve on a predefined background cosmology, commonly taken as the homogeneous-isotropi…
