Ekpyrotic and Cyclic Cosmology
by Jean-Luc Lehners
Publisher: arXiv 2009
Number of pages: 79
Description:
Ekpyrotic and cyclic cosmologies provide theories of the very early and of the very late universe. In these models, the big bang is described as a collision of branes - and thus the big bang is not the beginning of time. Before the big bang, there is an ekpyrotic phase with equation of state w=P/rho >> 1 during which the universe slowly contracts.

The Cosmic Web: Geometric Analysis
by Rien van de Weygaert, Willem Schaap - arXiv
The lecture notes describe the Delaunay Tessellation Field Estimator for Cosmic Web analysis. The high sensitivity of Voronoi/Delaunay tessellations to the local point distribution is used to obtain estimates of density and related quantities.

The Shape of the Universe
by Gerd Pommerenke - viXra
A special solution of the Maxwell equations is presented, which disposes of the properties the Higgs-field must have, if it should not violate already secured perceptions and observations. If both fields are identical remains to be seen at this time.
