Thus, it would appear that the method is very suitable to obtain infinite-dimensional Fatou lemmas as well. However, in extending the tightness approach to infinite-dimensional Fatou lemmas one is faced with two obstacles. A crucial tool for the Fatou's lemma. Let {fn}∞ n = 1 be a collection of non-negative integrable functions on (Ω, F, μ). Then, Monotone convergence theorem.

In Fatou’s lemma we get only an inequality for liminf’s and non-negative integrands, while in the dominated con- Fatou's research was personally encouraged and aided by Lebesgue himself. The details are described in Lebesgue's Theory of Integration: Its Origins and Development by Hawkins, pp.

The lemma is named after Pierre Fatou. Fatou's lemma can be used to prove the Fatou–Lebesgue theorem and Lebesgue's dominated convergence theorem. Fatou's Lemma, the Monotone Convergence Theorem (MCT), and the Dominated Convergence Theorem (DCT) are three major results in the theory of Lebesgue integration which answer the question "When do lim n→∞ lim n → ∞ and ∫ ∫ commute?" 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 Fatou’s Lemma Suppose fk 1 k=1 is a sequence of non-negative measurable functions.
