On the original Ulam's problem and its quantization
Changguang Dong, Jing Zhou
In this paper we show that under general resonance the classical piecewise linear Fermi-Ulam accelerator behaves substantially different from its quantization in the sense that the…
On the ergodic properties of time changes of partially hyperbolic homogeneous flows
Changguang Dong
For any accessible partially hyperbolic homogeneous flow, we show that all smooth time changes are K and hence mixing of all orders. We also establish stable ergodicity for time-on…
Flexibility of statistical properties for smooth systems satisfying the central limit theorem
Dmitry Dolgopyat, Changguang Dong, Adam Kanigowski +1
In this paper we exhibit new classes of smooth systems which satisfy the Central Limit Theorem (CLT) and have (at least) one of the following properties: (1) zero entropy; (2) weak…
Mixing properties of generalized transformations
Dmitry Dolgopyat, Changguang Dong, Adam Kanigowski +1
We study mixing properties of generalized transformation. We discuss two mixing mechanisms. In the case the fiber dynamics is mixing, it is sufficient that the driving…
Bernoulli property for certain skew products over hyperbolic systems
Changguang Dong, Adam Kanigowski
We study the Bernoulli property for a class of partially hyperbolic systems arising from skew products. More precisely, we consider a hyperbolic map , where is a Gibbs…
Rigidity of joinings for some measure preserving systems
Changguang Dong, Adam Kanigowski, Daren Wei
We introduce two properties: strong R-property and -property, describing a special way of divergence of nearby trajectories for an abstract measure preserving system. We show…
