متن کاملDistribution Des Préimages Et Des Points Périodiques D'une Correspondance Polynomiale
We construct an equilibrium measure µ for a polynomial correspondence F of Lojasiewicz exponent l > 1. We then show that µ can be built as the distribution of preimages of a generic point and that the expansive periodic points are equidistributed on the support of µ. Using this results, we will give a characterization of infinite unique sets for polynomials.
