Fatou's Lemma. Fatou's Lemma If is a sequence of nonnegative measurable functions, then (1) An example of a sequence of functions for which the inequality becomes strict is given by (2) Calculator; C--= π % 7: 8: 9: x^ / 4: 5: 6: ln * 1: 2: 3 √-± 0. Proof of Monotone Convergence Theorem, Fatous Lemma and the Dominated convergence theorem. Understand briefly how the Lebesgue integral connects with the Riemann one, and in particular when and why Riemann formulas can be used to evaluate Lebesgue integrals.

After viewing this picture, one can no longer worry about forgetting the direction of the inequality in Fatou’s Lemma!

Its –nite-dimensional generalizations have also received considerable attention in the literature of mathe-matics and economics; see, for example, [12], [13], [20], [26], [28] and [31]. Fatou’s lemma. Radon–Nikodym derivative.

Then Z f liminf Z fk Remarks: Condition fk 0 is necessary: fails for fk = ˜ [k;k+1] May be strict inequality: fk = ˜ [k;k+1] Most common way that Fatou is used: Corollary If fk(x) !f(x) pointwise, and R jfkj C for all k, then R jfj C The proof is based upon the Fatou Lemma: if a sequence {f k(x)} ∞ k = 1 of measurable nonnegative functions converges to f0 (x) almost everywhere in Ω and ∫ Ω fk (x) dx ≤ C, then f0is integrable and ∫ Ω f0 (x) dx ≤ C. We have a sequence fk (x) = g (x, yk (x)) that meets the conditions of this lemma. Fatou™s Lemma for a sequence of real-valued integrable functions is a basic result in real analysis. Its –nite-dimensional generalizations have also received considerable attention in the literature of mathe-matics and economics; see, for example, [12], [13], [20], [26], [28] and [31].

The last equation above uses the fact that if a sequence converges, all subsequences converge to the same limit. III.8: Fatou’s Lemma and the Monotone Convergence Theorem x8: Fatou’s Lemma and the Monotone Convergence Theorem. 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.
