Galileons from Lovelock actions
  We demonstrate how, for an arbitrary number of dimensions, the Galileon
actions and their covariant generalizations can be obtained through a standard
Kaluza-Klein compactification of higher-dimensional Lovelock gravity. In this
setup, the dilaton takes on the role of the Galileon. In addition, such
compactifications uncover other more general Galilean actions, producing purely
second-order equations in the weak-field limit, now both for the Galileon and
the metric perturbations.
