Kantowski-Sachs Einstein-{\ae}ther perfect fluid models
  We investigate Kantowski-Sachs models in Einstein-{\ae}ther theory with a
perfect fluid source using the singularity analysis to prove the integrability
of the field equations and dynamical system tools to study the evolution. We
find an inflationary source at early times, and an inflationary sink at late
times, for a wide region in the parameter space. The results by A. A. Coley, G.
Leon, P. Sandin and J. Latta (JCAP 12, 010, 2015), are then re-obtained as
particular cases. Additionally, we select other values for the non-GR
parameters which are consistent with current constraints, getting a very rich
phenomenology. In particular, we find solutions with infinite shear, zero
curvature, and infinite matter energy density in comparison with the Hubble
scalar. We also have stiff-like future attractors, anisotropic late-time
attractors, or both, in some special cases. Such results are developed
analytically, and then verified by numerics. Finally, the physical
interpretation of the new critical points is discussed.
