Asymptotic behaviour of Bianchi VI(o) solutions with an exponential potential scalar field
Luis P. Chimento, Pablo Labraga
We obtain some solutions to the Einstein-Klein-Gordon equations without a cosmological constant for an exponential potential scalar field in a Bianchi VI metric and investigate…
Assisted inflation in Bianchi VI0 cosmologies
J. M. Aguirregabiria, P. Labraga, Ruth Lazkoz
Exact models for Bianchi VI0 spacetimes with multiple scalar fields with exponential potentials have been derived and analysed. It has been shown that these solutions, when they ex…
General behaviour of Bianchi VI_0 solutions with an exponential-potential scalar field
Luis P. Chimento, Pablo Labraga
The solutions to the Einstein-Klein-Gordon equations without a cosmological constant are investigated for an exponential potential in a Bianchi VI_0 metric. There exists a two-para…
Scalar Field Inhomogeneous Cosmologies
A. Feinstein, J. Ibáñez, P. Labraga
Some exact solutions for the Einstein field equations corresponding to inhomogeneous cosmologies with an exponential-potential scalar field which generalize solutions obtaine…
