Birkhoff Averages and Rotational Invariant Circles for Area-Preserving Maps

Autor: Sander, E., Meiss, J. D.

Publikováno v: Physica D 411 132569 (2020)

Rotational invariant circles of area-preserving maps are an important and well-studied example of KAM tori. John Greene conjectured that the locally most robust rotational circles have rotation numbers that are noble, i.e., have continued fractions w

About periodic and quasi-periodic orbits of a new type for twist maps of the torus

Autor: SALVADOR ADDAS-ZANATA

Publikováno v: Anais da Academia Brasileira de Ciências, Vol 74, Iss 1, Pp 25-31 (2002)

We prove that for a large and important class of C¹ twist maps of the torus periodic and quasi-periodic orbits of a new type exist, provided that there are no rotational invariant circles (R.I.C's). These orbits have a non-zero "vertical rotation nu
