Estimate entropy of a binary process in terms of decay of correlations
Thanks, the process I want to understand has many other useful properties I can use, I was looking for minimal conditions. |

Approximating Moment of Sum of RVs
@Bill Johnson: absolutely, severe overkill. result must follow also from some easier inequalities as well. |

Approximating Moment of Sum of RVs
Look at Lemma 4, page 172, in Billingsley's book Convergence of probability measures. Lemma is for p=4, but it works for all even p. If I am not mistaken, this lemma gives the bound you are looking for. |

functions whose average along orbits is zero or a constant
the most famous example of a result of this nature is the so-called Livshic lemma: suppose $X$ is a mixing subshift, $T:X\to X$ is a left shift, and $f$ is a Holder-continuous function such that $$ \sum_{i=0}^{p-1} f(T^ix) =0 $$ for every periodic $x$: $x=T^px$. Then $f=g-g\circ T$. There are many generalizations of this result. |
