We consider skew product dynamical systems f:Θ×ℝ→Θ×ℝ,f(휃,y)=(T휃,f휃(y))" role="presentation">f:Θ×ℝ→Θ×ℝ,f(��,y)=(T��,f��(y)) with a (generalized) baker transformation T" role="presentation">T at the base and uniformly bounded increasing C3" role="presentation">C3 fibre maps f휃" role="presentation">f��
with negative Schwarzian derivative. Under a partial hyperbolicity
assumption that ensures the existence of strong stable fibres for f" role="presentation">f,
we prove that the presence of these fibres restricts considerably the
possible structures of invariant measures — both topologically and
measure theoretically, and that this finally allows to provide a
“thermodynamic formula” for the Hausdorff dimension of set of those base
points over which the dynamics are synchronized, i.e. over which the
global attractor consists of just one point.
