Se p 20 06 Singularities of varying light speed cosmologies

We study the possible singularities of isotropic cosmological models that have a varying speed of light as well as a varying gravitational constant. The field equations typically reduce to two dimensional systems which are then analyzed both by dynamical systems techniques in phase space and by applying the method of asymptotic splittings. In the general case we find initially expanding closed ...

New results on φ-meson production and elliptic flow v 2 measurements from RHIC 2004 run (Run-IV) have been reviewed. In addition, the di-hadron correlation function between the trigged φ and Ω and the associated soft particles was simulated. Knowledge about these results are discussed.
