Local equilibrium in planar non interacting particle systems

Péter Nándori, Trevor Teolis

Particles are injected to a large planar rectangle through the boundary. Assuming that the particles move independently from one another and the boundary is also absorbing, we iden…

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…

Statistical properties of type D dispersing billiards

Margaret Brown, Péter Nándori

We consider dispersing billiard tables whose boundary is piecewise smooth and the free flight function is unbounded. We also assume there are no cusps. Such billiard tables are cal…

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…

Asymptotic expansion of correlation functions for covers of hyperbolic flows

Dmitry Dolgopyat, Péter Nándori, Françoise Pène

We establish expansion of every order for the correlation function of sufficiently regular observables of extensions of some hyperbolic flows. Our examples include th…

Global observables for random walks: law of large numbers

Dmitry Dolgopyat, Marco Lenci, Péter Nándori

We consider the sums where is a random walk on and is a global observable, that is, a bounded function wh…
