Generalized Assisted Inflation
arXiv:astro-ph/9904309 · doi:10.1103/PhysRevD.60.083506
Abstract
We obtain a new class of exact cosmological solutions for multi-scalar fields with exponential potentials. We generalize the assisted inflation solutions previously obtained, and demonstrate how they are modified when there exist cross-couplings between the fields, such as occur in supergravity inspired cosmological models.
