Applications of Cesaro's lemma to probability theory

75 Views Asked by At

I am currently trying to collect applications of Cesaro's lemma to various fields.

I suspect that there are (elementary) applications of this lemma to probability theory but couldn't find any.

Suggestions and references would be highly appreciated.

  • A consequence of Cesàro's lemma is Kronecker's, which can be used to prove laws of large numbers.

  • I can think of two related (negative) results:

  1. A sequence of i.i.d. random variables cannot converge almost surely, unless it is a deterministic sequence.

  2. If a sequence of random variables converges in probability, then it is not necessary true for its Cesàro mean.
