FATOU’S IDENTITY AND LEBESGUE’S CONVERGENCE THEOREM 2299 Proposition 3. Let f =(fn)be a bounded sequence in L1 (P) converging in mea- sure to f1.Then the following equality holds: limn!+1 Z fndP =minf (f^):f^subsequence of fg+ Z f1dP: Proof. We simply apply Lemma 1 and Lemma 2 to a subsequence (f0 n

Support the channel on Steady: https://steadyhq.com/en/brightsideofmaths Official supporters in this The current line of research was initially motivated by the limitations of the existing applications of Fatou’s lemma to dynamic optimization problems (e.g., [ 11, 12 ]). In particular, there are certain cases in which optimal paths exist but the standard version of Fatou’s lemma fails to apply. 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 .} (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. 2.

Proposition.

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?"

(2) SEE ALSO: Almost Everywhere Convergence, Measure Theory, Pointwise Convergence REFERENCES: Browder, A. Mathematical Analysis: An Introduction. 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]. What you showed is that Fatou's lemma implies the mentioned property.
