Before prooving BCL, notice that 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. 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.

Their interests lie in nding more generalized versions of the Borel-Cantelli lemmas. There are a number of ways in one can generalize the Borel-Cantelli lemmas, some of which we will see in this article. But rst let us look at the standard version of the Borel-Cantelli lemmas. 1.2 The Standard Version Of The Borel-Cantelli En particulier, le lemme de Borel-Cantelli donné en introduction est une forme affaiblie du théorème de Borel-Cantelli donné à la section précédente.
