General solution to two-scalar field cosmologies with exponential potentials

We find the exact general solution for cosmological models arising from the interaction of the gravitational field with two scalar fields in both flat Robertson-Walker and the locally rotationally symmetric Bianchi I spacetime filled with an exponential potential. One scalar field self-interacts wit...

description We find the exact general solution for cosmological models arising from the interaction of the gravitational field with two scalar fields in both flat Robertson-Walker and the locally rotationally symmetric Bianchi I spacetime filled with an exponential potential. One scalar field self-interacts with this potential and the other is a free massless scalar field. The solutions have a singularity and a set of these exhibit the transition to power-law inflation for both metrics.
