Query: $\mathcal{N}$-field cosmology in hyperbolic field space: stability and
  general solutions   We study the dynamics of a cosmological model with a perfect fluid and
$\mathcal{N}$ fields on a hyperbolic field space interacting via a symmetric
potential. We list all late-time solutions, investigate their stability and
briefly discuss predictions of the theory. Moreover, for the case of two scalar
fields and an exponential potential we prove that the field equations are
Liouville integrable and we provide for the first time the general solution for
a region of the parameter space.
