Title: *Optimization of ergodic averages along squares.*

Abstract: Given a real-valued function defined on the phase space of a
dynamical system, ergodic optimization is the study of the orbits that maximize the
ergodic -time-average. It turns out that this is equivalent in maximizing the space
average over all invariant probability measures. In this talk, we will consider the
question of maximization of non-conventional ergodic averages along square iterates.
In particular, we will look at the doubling map for characteristic functions centered
at 1/2, when varying the
initial state from the set in which the operator has good asymptotic behavior.
