Construction of equilibrium states revisited
Changguang Dong, Qiujie Qiao
In [52], Parmenter and Pollicott establish an abstract criterion that gives a geometric construction of equilibrium states for a class of partially hyperbolic systems. We refine th…

Slow entropy for abelian actions
Changguang Dong, Qiujie Qiao
We calculate slow entropy type invariant introduced by A. Katok and J.-P. Thouvenot in [5] for higher rank smooth abelian actions for two leading cases: when the invariant measure…

On -Neutralized Entropy: Entropy Formula and Existence of Measures Attaining the Supremum
Changguang Dong, Qiujie Qiao
In this article we study -neutralized local entropy and derive some entropy formulas. For an ergodic hyperbolic measure of a smooth system, we show that the -neutralized loca…
