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.

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. LEMMA 26. The sequence of random variables (T n n) n ≥ 1 converges P ˜ μ − a. s. to (1 + m) as n → +∞. Proof:

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.

Convergence in probability subsequential a.s. convergence I Theorem: X n!X in probability if and only if for every subsequence of the X n there … We prove some conditional Borel–Cantelli lemmas for sequences of random variables. As an application, a conditional version of the weighted Borel–Cantelli lemma is obtained. The Borel-Cantelli lemmas are a set of results that establish if certain events occur inﬁnitely often or only ﬁnitely often. We present here the two most well-known versions of the Borel-Cantelli lemmas.

2 The Borel-Cantelli lemma and applications Lemma 1 (Borel-Cantelli) Let fE kg1 k=1 be a countable family of measur- able subsets of Rd such that X1 k=1 m(E k) <1 Then limsup k!1 (E k) is measurable and has measure zero. Proof. Given the identity,

= 0. Et andet resultat er det andet Borel-Cantelli-lemma, der siger, at det modsatte delvist gælder: Hvis E n er uafhængige hændelser og summen af sandsynlighederne for E n divergerer mod uendelig, så er sandsynligheden for, at uendeligt mange af hændelserne indtræffer lig 1. The Borel-Cantelli lemmas are a set of results that establish if certain events occur inﬁnitely often or only ﬁnitely often. We present here the two most well-known versions of the Borel-Cantelli lemmas. Lemma 10.1(First Borel-Cantellilemma) Let {A n} be a sequence of events such that P∞ n=1 P(A n) <∞. Then, almost surely, only Since $\{A_n \:\: i.o\}$ is a tail event, combined with Borel-Cantelli lemma, it is clear that the second Borel-Cantelli lemma is equivalent to the converse of the first one.

Definition 1 Let {Ek}∞. We give a version of the Borel-Cantelli lemma. As an application, we prove an almost sure local central limit theorem.

Then E(S) = \1 n=1 [1m= Em is the limsup event of the inﬂnite sequence; event E(S) occurs if and only if † for all n ‚ 1, there exists an m ‚ n such that Em occurs. † inﬂnitely many of the En occur.
