Analytic solutions in Einstein-aether scalar field cosmology
  In the context of Einstein-aether scalar field cosmology we solve the field
equations and determine exact and analytic solutions. In particular, we
consider a model proposed by Kanno and Soda where the aether and the scalar
fields interact through the aether coefficient parameters, which are promoted
to be functions of the scalar field. For this model, we write the field
equations by using the minisuperspace approach and we determine the scalar
field potentials which leads to Liouville--integrable systems. We solve the
field equations for five families of scalar field potentials and, whether it is
feasible, we write down the analytic solutions by using closed-form functions.
