The embedding flows of hyperbolic diffeomorphisms
Zhang Xiang
In [{\it American J. Mathematics}, 124(2002), 107--127] we proved that for a germ of hyperbolic diffeomorphisms in , if has a real lo…
Generalized rational first integrals of analytic differential systems
Wang Cong, Jaume Llibre, Xiang Zhang
In this paper we mainly study the necessary conditions for the existence of functionally independent generalized rational first integrals of ordinary differential systems via the r…
The th Hilbert problem on algebraic limit cycles
Zhang Xiang
For real planar polynomial differential systems there appeared a simple version of the th Hilbert problem on algebraic limit cycles: {\it Is there an upper bound on the number…
Analytic integrable systems: Analytic normalization and embedding flows
Zhang Xiang
In this paper we mainly study the existence of analytic normalization and the normal form of finite dimensional complete analytic integrable dynamical systems. More details, we wil…
