Das Borel-Cantelli-Lemma, manchmal auch Borel’sches Null-Eins-Gesetz, (nach Émile Borel und Francesco Cantelli) ist ein Satz der Wahrscheinlichkeitstheorie. Es ist oftmals hilfreich bei der Untersuchung auf fast sichere Konvergenz von Zufallsvariablen und wird daher für den Beweis des starken Gesetzes der großen Zahlen verwendet.

Borel-Cantelli Lemmas . 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

Similarly, let E(I) = [1 n=1 \1 m=n Em 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. First Borel-Cantelli Lemma Posted on January 4, 2014 by Jonathan Mattingly | Comments Off on First Borel-Cantelli Lemma The first Borel-Cantelli lemma is the principle means by which information about expectations can be converted into almost sure information.

Il Lemma di Borel-Cantelli è un risultato di teoria della probabilità e teoria della misura fondamentale per la dimostrazione della legge forte dei grandi numeri. Siano ( Ω , E , μ ) {\displaystyle (\Omega ,{\mathcal {E}},\mu )} uno spazio di misura e { S n } n ∈ N {\displaystyle \{S_{n}\}_{n\in \mathbb {N} }} una successione di sottoinsiemi misurabili di Ω {\displaystyle \Omega } .
