稀疏随机子序列的L^1遍历定理

An L^1 Ergodic Theorem for Sparse Random Subsequences

Patrick LaVictoire

摘要:

我们证明了由独立随机选择变量选择的序列的L^1子序列遍历定理,从而证明了几乎像平方集一样稀疏的普遍L^1-好序列的存在性。在这个过程中,我们证明了一定的确定性条件蕴含着一个弱极大不等式的\ell^1卷积算子序列。

英文摘要:

We prove an L^1 subsequence ergodic theorem for sequences chosen by independent random selector variables, thereby showing the existence of universally L^1-good sequences nearly as sparse as the set of squares. In the process, we prove that a certain deterministic condition implies a weak maximal inequality for a sequence of \ell^1 convolution operators.
