Abstract: | We introduce a new class of adelic heights on the projective line. We estimate their essential minimum and prove a result
of equidistribution (at every place) for points of small height with estimates on the speed of convergence. To each rational
function R in one variable and defined over a number field K, is associated a normalized height on the algebraic closure of K. We show that these dynamically defined heights are adelic in our sense, and deduce from this equidistribution results for
preimages of points under R at every place of K. Our approach follows that of Bilu, and relies on potential theory in the complex plane, as well as in the Berkovich space
associated to the projective line over , for each prime p.
