The classical Borel–Cantelli lemma is a fundamental tool for many conver- gence theorems in probability theory. For example, the lemma is applied in the standard

The Borel Cantelli Lemma says that if the sum of the probabilities of the { E n } are finite, then the collection of outcomes that occur infinitely often must have probability zero. To give an example, suppose I randomly pick a real number x ∈ [ 0, 1] using an arbitrary probability measure μ.

What is confusing me is what ‘probability of the limit superior equals $ The classical Borel–Cantelli lemma is a beautiful discovery with wide applications in the mathematical field. The Borel–Cantelli lemmas in dynamical systems are particularly fascinating. Here, D. Kleinbock and G. Margulis have given an important sufficient condition for the strongly Borel–Cantelli sequence, which is based on the work of W. M. Schmidt. The Borel-Cantelli lemmas 1.1 About the Borel-Cantelli lemmas Although the mathematical roots of probability are in the sixteenth century, when mathe-maticians tried to analyse games of chance, it wasn’t until the beginning of the 1930’s before there was a solid mathematical axiomatic foundation of probability theory. The beginning of 2020-12-21 · In probability theory, the Borel–Cantelli lemma is a theorem about sequences of events.In general, it is a result in measure theory.

The celebrated Borel-Cantelli lemma asserts that (A) If ZPiEk) < oo, then P (lim sup Ek) =0; (B) If the events Ek are independent and if Z-^C-^fc)= °° > then P(lim sup Ek) = l. In intuitive language P(lim sup Ek) is the probability that the events Ek occur "infinitely often" and will be denoted by P(Ek i.o.).

Recently, V. | Find It is known that the Borel–Cantelli Lemma plays an important role in probability theory. Many attempts were made to generalize its second part. In this article, we Mar 26, 2019 The First and Second Borel-Cantelli Lemmas are both used to show that For the following lemma to be used in the proof of Theorem 2.1, see This monograph provides an extensive treatment of the theory and applications of the celebrated Borel-Cantelli Lemma. Starting from some of the basic facts of The second Borel-Cantelli lemma has the additional condition that the events are mutually independent.
