8 Aug 2018 Fatou's Lemma: If the r.v.'s X n satisfy X n ≥ Y a.s. ( Y ∈ L 1 ) , all n , we have E [ l i m i n f n → ∞ X n ] ≤ l i m i n f n → ∞ E [ X n ] . In particular,

The only Fatou's Lemma Im familier with is Fatou's Lemma for events, that is, if (A n) n is a sequence of events, we have: P (lim inf n A n) ≤ lim inf n P (A n) ≤ lim sup n P (A n) ≤ P (lim sup n A n) But more importent, I cant see why the first inequallity I mentioned holds. I can find a counter example;

Then E[lim infn Xn] ≤ lim infn EXn ≤ ∞. Proof. Define YN = infn≥N Xn. Then 0 ≤ YN ↑ lim inf Xn, so 0 Indeed (5) may remind you of Fatou's Lemma from Part A. 1 Measure spaces.

The examples in this paper demonstrate that: (a) the uniform Fatou lemma may indeed provide a more accurate inequality than the classic Fatou lemma; (b) the uniform Fatou lemma does not hold if convergence of measures in total variation is relaxed to setwise convergence. We should mention that there are other important extensions of Fatou’s lemma to more general functions and spaces (e.g., [3, 2, 16]). However, to our knowledge, there is no result in the literature that covers our generalization of Fatou’s lemma, which is speci c to extended real-valued functions.

use the theorems about monotone and dominated convergence, and Fatou's lemma;; describe the construction of product measures;; use Fubini's theorem;

Fatou’s lemma and the dominated convergence theorem are other theorems in this vein, where monotonicity is not required but something else is needed in its place. In Fatou’s lemma we get only an inequality for liminf’s and non-negative integrands, while in the dominated con- 2007-08-20 · A general Fatou Lemma is established for a sequence of Gelfand integrable functions from a vector Loeb space to the dual of a separable Banach space or, with a weaker assumption on the sequence, a Banach lattice. A corollary sharpens previous results in the finite-dimensional setting even for the case of scalar measures.

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.

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. With monotonicity in the sequence of functions

It plays an important technical role in the usual proofs of competitive equilibrium exis-tence. Related versions of Fatou’s lemma were given by Artstein and Hildenbrand-Mertens [1, 24], and in [3] a version was given that subsumes the aforementioned ones. Pierre Joseph Louis Fatou (28 February 1878 – 9 August 1929) was a French mathematician and astronomer. He is known for major contributions to several branches of analysis.
