本文研究了一类Hölder连续函数在具有定常平衡态的有限型移位上的中心极限定理的收敛速度和渐近展开式。证明了定理的收敛速度为O(n−1/2),并且当函数定义为非格分布时,给出了阶为O(n−1/2)的渐近展开式。高阶展开式可以由函数的子类得到。我们还对(闭)轨道测度的中心极限定理进行了评论。
We study the rate of convergence and asymptotic expansions in the central limit theorem for the class of Hölder continuous functions on a shift of finite type endowed with a stationary equilibrium state. It is shown that the rate of convergence in the theorem isO(n−1/2) and when the function defines a non-lattice distribution an asymptotic expansion to the order ofo(n−1/2) is given. Higher-order expansions can be obtained for a subclass of functions. We also make a remark on the central limit theorem for (closed) orbital measures.
