Rational diffeomorphisms of the circle

چکیده
We prove an interpolation theorem for rational circle diffeomorphisms: A set of N complex numbers of unit modulus may be mapped to any corresponding set by a ratio of polynomials p(z)/q(z) which restricts an invertible mapping of the unit circle S ⊂ C onto itself.

Dimensional Characteristics of Invariant Measures for Circle Diffeomorphisms
We consider pointwise, box, and Hausdorff dimensions of invariant measures for circle diffeomorphisms. We discuss the cases of rational, Diophantine, and Liouville rotation numbers. Our main result is that for any Liouville number τ there exists a C∞ circle diffeomorphism with rotation number τ such that the pointwise and box dimensions of its unique invariant measure do not exist. Moreover, th...
متن کاملA Denjoy Theorem for commuting circle diffeomorphisms with mixed Hölder derivatives
Starting from the seminal works by Poincaré [13] and Denjoy [3], a deep theory for the dynamics of circle diffeomorphisms has been developed by many authors [1, 7, 8, 17], and most of the fundamental related problems have been already solved. Quite surprisingly, the case of several commuting diffeomorphisms is rater special, as it was pointed out for the first time by Moser [9] in relation to t...
متن کاملOn the numerical computation of Diophantine rotation numbers of analytic circle maps
In this paper we present a numerical method to compute Diophantine rotation numbers of circle maps with high accuracy. We mainly focus on analytic circle diffeomorphisms, but the method also works in the case of (enough) finite differentiability. The keystone of the method is that, under these conditions, the map is conjugate to a rigid rotation of the circle. Moreover, albeit it is not fully j...
متن کامل-generic Diffeomorphisms
On the one hand, we prove that the spaces of C 1 symplectomor-phisms and of C 1 volume-preserving diffeomorphisms both contain residual subsets of diffeomorphisms whose centralizers are trivial. On the other hand, we show that the space of C 1 diffeomorphisms of the circle and a non-empty open set of C 1 diffeomorphisms of the two-sphere contain dense subsets of diffeomorphisms whose centralize...
