$\mathbb {R}^d$上截尾滤的熵的鞅界

A martingale bound for the entropy associated with a trimmed filtration on $\mathbb {R}^d$

Alexei Kulik, Taras Tymoshkevych

摘要:

利用鞅方法,我们提供了$\mathbb {R}^d$上概率测度的熵的界,其右端以某种积分形式给出。作为推论,在一维情形下,我们得到了一个加权log-Sobolev不等式。

英文摘要:

Using martingale methods, we provide bounds for the entropy of a probability measure on $\mathbb {R}^d$ with the right-hand side given in a certain integral form. As a corollary, in the one-dimensional case, we obtain a weighted log-Sobolev inequality.
