Brans-Dicke cosmology with a scalar field potential
arXiv:gr-qc/0210087 · doi:10.1209/epl/i2002-00664-2
Abstract
Three solutions of the Brans-Dicke theory with a self-interacting quartic potential and perfect fluid distribution are presented for a spatially flat geometry. The physical behavior is consistent with the recent cosmological scenario favored by type Ia supernova observations, indicating an accelerated expansion of the Universe.
