Conformal Cosmology and Supernova Data — •Danilo Behnke¹, David Blaschke¹, Victor N. Pervushin², and Denis Proskurin² — ¹Universität Rostock, 18051 Rostock — ²BLTP, JINR, 141980 Dubna, Russia

We define the cosmological parameters H_c,0, Ω_m,c and Ω_{Λ ,c} within the Conformal Cosmology as obtained by the homogeneous approximation to the conformal- invariant generalization of Einstein’s General Relativity theory. We present the definitions of the age of the universe and of the luminosity distance in the context of this approach. A possible explanation of the recent data from distant supernovae Ia without a cosmological constant is presented [1].
