An exact Lagrangian integral for the Newtonian gravitational field strength
Thomas Buchert
An exact expression for the gravitational field strength in a self-gravitating dust continuum is derived within the Lagrangian picture of continuum mechanics. From the Euler-Newton…
The universe seen at different scales
G. F. R. Ellis, T. Buchert
A large-scale smoothed-out model of the universe ignores small-scale inhomogeneities, but the averaged effects of those inhomogeneities may alter both observational and dynamical r…
A cosmic equation of state for the inhomogeneous Universe: can a global far-from-equilibrium state explain Dark Energy?
Thomas Buchert
A system of effective Einstein equations for spatially averaged scalar variables of inhomogeneous cosmological models can be solved by providing a `cosmic equation of state'. Recen…
Adhesive Gravitational Clustering
Thomas Buchert, Alvaro Dominguez
The notion of `adhesion' has been advanced for the phenomenon of stabilization of large-scale structure emerging from gravitational instability of a cold medium. Recently, the phys…
Information Entropy in Cosmology
Akio Hosoya, Thomas Buchert, Masaaki Morita
The effective evolution of an inhomogeneous cosmological model may be described in terms of spatially averaged variables. We point out that in this context, quite naturally, a meas…
The Cosmic Quartet - Cosmological Parameters of a Smoothed Inhomogeneous Spacetime
Thomas Buchert, Mauro Carfora
We discuss the relation between `bare' cosmological parameters as the true spatial average characteristics that determine the cosmological model, and the parameters interpreted by…
