Once we have understood limit inferior/superior of sequence of sets and the continuity property of probability measure, proving the Borel-Cantelli Lemmas is straightforward. So, here are the lemmas and their proof. Theorem(First Borel-Cantelli Lemma) Let $(\Omega, \mathcal F In probability theory, the Borel–Cantelli lemma is a theorem about sequences of events. In general, it is a result in measure theory. It is named after Émile Borel and Francesco Paolo Cantelli, who gave statement to the lemma in the first decades of the 20th century. A related result, sometimes called the second Borel–Cantelli lemma, is a partial converse of the first Borel–Cantelli We choose r = 4 and thus from Borel-Cantelli Lemma, we deduce that S n − m Z n n converges almost surely to 0 as n goes to infinity. To get the result for the simple random walk (M n) n, we use the.

DOI: 10.1215/ijm The special feature of the book is a detailed discussion of a strengthened form of the second Borel-Cantelli Lemma and the conditional form of the Borel-Cantelli Lemmas due to Levy, Chen and Serfling. All these results are well illustrated by means of many interesting examples. All the proofs are rigorous, complete and lucid.
