Lp. Chimento et P. Labraga, GENERAL BEHAVIOR OF BIANCHI VI0 SOLUTIONS WITH AN EXPONENTIAL-POTENTIAL SCALAR FIELD, General relativity and gravitation, 30(10), 1998, pp. 1535-1541
The solutions to the Einstein-Klein-Gordon equations without a cosmolo
gical constant are investigated for an exponential potential in a Bian
chi VIo metric. There exists a two-parameter family oi solutions which
have a power-law inflationary behaviour when the exponent of the pote
ntial, k, satisfies k(2) < 2. In addition, there exists a two-paramete
r family of singular solutions for all k(2) values. A simple anisotrop
ic exact solution is found to be stable when 2 < k(2) .
