WebTheorem A, with property (v′ ) below added to the conclusions, extends the main theorem from the paper [PZ], where the density of periodic orbits in Fr Ω was proved. The idea of the proof, as in [PZ], is to apply Pesin and Katok theories; see [HK, Suplement] for a general theory and [PU, Ch. 9] for its adaptation in holomorphic iteration. WebThe rotation set for a Birkhoff recurrence class is a singleton and the forward and backward rotation numbers are identical for each solution in the same Birkhoff recurrence class. We also show the continuity of rotation numbers on the set of non-wandering points.
WebThe proof of the "ergodic theorem," that there is a time-probability p that a point P of a general trajectory lies in a given volume v of AM, parallels that of the above recurrence theorem, as will be seen. The important recent work of von Neumann (not yet published) shows only that there is convergence in the mean, so that (1) is not proved by WebKenneth Williams. George David Birkhoff (March 21, 1884 – November 12, 1944) was an American mathematician best known for what is now called the ergodic theorem. Birkhoff was one of the most important leaders in …

WebWith this realization, we extend the classical Birkhoff Recurrence Theorem to the case of semiflows. And following this result, we give the main theorem (Theorem 3.3) for the existence and location of recurrent solutions of a general nonautonomous differential equation with a recurrent forcing. It is stated
