For an iid IFS of continuous maps on the circle we discuss if
and how a metric change can turn the system into one which contracts on
average. In particular, we discuss the case of a system of C1
diffeomorphisms of maps which is proximal and does not preserve a common
measure. In this case the IFS is exponentially synchronizing. We discuss
how such techniques can be used to derive limit laws such as a quenched
central limit theorem and we describe some large deviation results of
synchronization rates and finite time Lyapunov exponents. This is joint
work with Graccyela Salcedo (USP-São Carlos).
