Now, combining (3) with (1) and (2) yields: hence, therefore. which proves everything that We should mention that there are other important extensions of Fatou’s lemma to more general functions and spaces (e.g., [13–15]). However, to our knowledge, there is no result in the literature that covers our generalization of Fatou’s lemma, which is specific to extended real-valued functions. 2016-10-03 · By Fatou’s Lemma, a contradiction. The last equation above uses the fact that if a sequence converges, all subsequences converge to the same limit. Fatou's lemma and Borel set · See more » Conditional expectation In probability theory, the conditional expectation, conditional expected value, or conditional mean of a random variable is its expected value – the value it would take “on average” over an arbitrarily large number of occurrences – given that a certain set of "conditions" is known to occur.

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 (b) Deduce the dominated Convergence Theorem from Fatou’s Lemma. Hint: Ap-ply Fatou’s Lemma to the nonnegative functions g + f n and g f n.

He is known for major contributions to several branches of analysis. The Fatou lemma and the Fatou set are named after him.

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.
