The only Fatou's Lemma Im familier with is Das Lemma von Fatou (nach Pierre Fatou) erlaubt in der Mathematik, das Lebesgue-Integral des Limes inferior einer Funktionenfolge durch den Limes inferior der Folge der zugehörigen Lebesgue-Integrale nach oben abzuschätzen. Es liefert damit eine Aussage über die Vertauschbarkeit von Grenzwertprozessen. 这一节单独来介绍一下 Fatou 引理 (Fatou's Lemma)。. Theorem 7.8 设 是非负可测函数，那么. 证：令 , 则 也是非负; 由 Proposition 5.8， 也是可测的; 且 。 , 故 。. 于是我们有： (式 7.2)。.

(1970), Hildenbrand (1974)   Prove the reverse Fatou lemma, i.e. if (fn) is a sequence of non-negative rem, Fatou's lemma and the dominated convergence theorem, using random  extend the result of Kato [4], use that extension to prove a Fatou's lemma for Banach space valued' multifunctions, extending this way the works of. Schmeidler. One purpose of this paper is to derive analogues of Fatou's Lemma and of the Mono- tone and the dominated Convergence Theorems formeasures instead of  18 Nov 2013 Fatou's lemma. Let {fn}∞n=1 be a collection of non-negative integrable functions on (Ω,F,μ).

Let {fn}∞n=1 be a collection of non-negative integrable functions on (Ω,F,μ). Then, ∫lim infn→∞fndμ≤lim infn→∞∫fndμ. 29 Nov 2014 As we have seen in a previous post, Fatou's lemma is a result of measure theory, which is strong for the simplicity of its hypotheses.

1.5 Theorem (Fatou’s lemma). If X 1;X 2;:::are nonnegative random variables, then Eliminf n!1 X n liminf n!1 EX n: Proof. Let Y n= inf k nX k. Then this is a nondecreasing sequence which converges to liminf n!1X nand Y n X n. Note that liminf n!1 EX n liminf n!1 EY n= lim n!1 EY n; where the last equality holds because the sequence EY n, as

We will present these results in a manner that di ers from the book: we will rst prove the Monotone Convergence Theorem, and use it to prove Fatou’s Lemma. Proposition.

Last time defined expectation and stated Monotone Convergence Theorem, Dominated Convergence Theorem and Fatou's Lemma. Reviewed elementary 

Then liminf n!1 Z R f n d Z R liminf n!1 f n d Proof. Let g n(x) = inf k n f k(x) so that what we mean by liminf n!1f n is the function with Generalized Fatou’s Lemma. If {f n} is a sequence of nonnegative measurable functions on E, then Z E liminf f n ≤ liminf Z E f n. Note. We see from the example given in Note 4.3.A that we need some extra conditions beyond pointwise converge to get a convergence theorem for Class 2 functions.
