Lemma 10.6 (Fatou's Lemma). Take arbitrary Xn ≥ 0. Then E[lim infn Xn] ≤ lim infn EXn ≤ ∞. Proof. Define YN = infn≥N Xn. Then 0 ≤ YN ↑ lim inf Xn, so 0

Fatou’s lemma in ßnitely many dimensions goes back to Aumann [2] and Schmeidler [32]. 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. The Fatou lemma and the Fatou set are named after him. 2012-07-27 · [Fa] P. Fatou, "Séries trigonométriques et séries de Taylor" Acta Math., 30 (1906) pp.

In matematica, il lemma di Fatou è un lemma che stabilisce una disuguaglianza tra l'integrale di Lebesgue del limite inferiore di una successione di funzioni e il limite inferiore degli integrali di queste funzioni. Il lemma porta il nome del matematico francese Pierre Fatou (1878 - 1929).

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. Fatous lemma är en olikhet inom matematisk analys som förkunnar att om är ett mått på en mängd och är en följd av funktioner på , mätbara med avseende på , så gäller ∫ lim inf n → ∞ f n d μ ≤ lim inf n → ∞ ∫ f n d μ . {\displaystyle \int \liminf _{n\rightarrow \infty }f_{n}\,\mathrm {d} \mu \leq \liminf _{n\to \infty }\int f_{n}\,\mathrm {d} \mu .} Fatou's Lemma: Let (X,Σ,μ) ( X, Σ, μ) be a measure space and {f n: X → [0,∞]} { f n: X → [ 0, ∞] } a sequence of nonnegative measurable functions. Then the function lim inf n→∞ f n lim inf n → ∞ f n is measureable and ∫X lim inf n→∞ f n dμ ≤ lim inf n→∞ ∫X f n dμ. ∫ X lim inf n → ∞ f n d μ ≤ lim inf n → ∞ ∫ X f n d μ.

Das Lemma von Fatou (nach Pierre Fatou) erlaubt in der Mathematik, das Lebesgue-Integral des Limes inferior einer Funktionenfolge durch den Limes inferior der Folge der zugehörigen Lebesgue-Integrale nach oben abzuschätzen. Es liefert damit eine Aussage über die Vertauschbarkeit von Grenzwertprozessen.
