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]. In mathematics, Fatou's lemma establishes an inequality relating the Lebesgue integral of the limit inferior of a sequence of functions to the limit inferior of integrals of these functions.

As in the proof of the DCT we can assume that all  State Fatou's lemma and the monotone convergence theorem, and prove that each implies the other. 2. Suppose fn → f a.e. and f is integrable. Prove that if this   and negative parts of Ri and I). Thus it suffices to prove the theorem for nonnegative functions fi and f.

Ökenblomma med ett viktigt budskap | Fatou.se  In mathematics, Fatou's lemma establishes an inequality relating the Lebesgue integral of the limit inferior of a sequence of functions to the limit inferior of integrals of these functions. 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.
