New Integrable Chiral Cosmological Models with Two Scalar Fields
Vsevolod R. Ivanov, Sergey Yu. Vernov
We construct integrable chiral cosmological models with two scalar fields and potentials represented in terms of hyperbolic functions. Using the conformal transformation of the met…

Integrable Cosmological Models with an Arbitrary Number of Scalar Fields
V. R. Ivanov, S. Yu. Vernov
We consider cosmological models with an arbitrary number of scalar fields nonminimally coupled to gravity and construct new integrable cosmological models. In the constructed model…
