    Notes: Abstract The objective of this note is to present some results, to be proved in a forthcoming paper, about certain special solutions of the Euler-Lagrange equations on closed manifolds. Our main results extend to time dependent periodic Lagrangians with minor modifications. We have chosen the autonomous case because this formally simpler framework allows to reach more easily the core of our concepts and results. Moreover the autonomous case exhibits certain special features involving the energy as a first integral that deserve special attention. They are closely related to the link found by Carneiro [C] between the energy and Mather's action function [Ma].

    Notes: Abstract We prove a result on the backward dynamics of a rational function nearby a point not contained in the ω-limit set of a recurrent critical point. As a corollary we show that a compact invariant subset of the Julia set, not containing critical or parabolic points, and not intersecting the ω-limit set ofrecurrent critical points, is expanding, thus extending a classical criteria of Fatou. We also prove that the boundary of a Siegel disk is always contained in the ω-limit set of arecurrent critical point.

    Notes: Abstract Letf be aC 2 map of the circle or the interval and letΣ(f) denote the complement of the basins of attraction of the attracting periodic orbits. We prove thatΣ(f) is a hyperbolic expanding set if (and obviously only if) every periodic point is hyperbolic andΣ(f) doesn't contain the critical point. This is the real one dimensional version of Fatou's hyperbolicity criteria for holomorphic endomorphisms of the Riemann sphere. We also explore other applications of the techniques used for the result above, proving, for instance, that for everyC 2 immersionf of the circle (i.e. a map of the circle onto itself without critical points), either its Julia set has measure zero or it is the whole circle and thenf is ergodic, i.e. positively invariant Borel sets have zero or full measure.
