Abstract

UNIMODAL MAPS INVARIANT-MEASURES NEGATIVE SCHWARZIAN QUADRATIC MAPS CANTOR SETS DYNAMICS ATTRACTORS GEOMETRY DECAY
We show that for a one-parameter family of unicritical polynomials {fc} with even critical order ℓ⩾2, for almost all parameters c, fc admits a unique SRB-measure, being either absolutely continuous, or supported on the postcritical set. As a by product we prove that if fc has a Cantor attractor, then it is uniquely ergodic on its postcritical set.
