Lebesgue Integrability and Convergence

Lebesgue’s dominated convergence theorem is a crucial pillar of modern analysis, but there are certain areas of the subject where this theorem is deficient. Deeper criteria for convergence of integrals are described in this article.

The dominated convergence theorem and applica-tions The Monotone Covergence theorem is one of a number of key theorems alllowing one to ex-change limits and [Lebesgue] integrals (or derivatives and integrals, as derivatives are also a sort of limit).

Lebesgue Dominated Convergence Theorem, which states that when a sequence ff ngof Lebesgue measurable functions is bounded by a Lebesgue integrable function, the function f obtained as the pointwise limit f n is also Lebesgue integrable, and R lim nf n= f= lim n f n.

The great theorem on convergence of integrals is due in its usual form to Lebesgue [2] though its origins go back to Arzela [1]. It says that the integral of the limit of a sequence of functions is the limit of the integrals if the sequence is dominated by an integrable function.

Highlights We present a proof of Lebesgue’s dominated convergence theorem. The proof is presented in the abstract setting of ordered uniform spaces. The proof is done constructively in intuitionistic logic and in Bishop’s style. We do not employ any axiom of choice or impredicative construction. The proof generalises and

Lebesgue Dominated Convergence Theorem, which states that when a sequence ff ngof Lebesgue measurable functions is bounded by a Lebesgue integrable function, the function f obtained as the pointwise limit f n is also Lebesgue integrable, and R lim nf n= f= lim n f n.

Thus, f n ≤ M, for all n. Since f n → f0 on [a,c], Lebesgue dominated convergence theorem gives Z c a f0 = lim n→∞ Z c a f n. Using the above lemmas and the continuity of f at a,c, we have

1 Introduction 1 Introduction Lebesgue’s dominated convergence theorem represents an important milestone for the develop-ment of measure theory and probability theory.
The great theorem on convergence of integrals is due in its usual form to Lebesgue [2] though its origins go back to Arzela [1]. It says that the integral of the limit of a sequence of functions is the limit of the integrals if the sequence is dominated by an integrable function.
Math 623: Homework 3 1. In class we rst proved the Bounded Convergence Theorem (using Egorov Theo- rem). We then proved Fatou’s Lemma (using the Bounded Convergence theorem) and deduced from it the Monotone Convergence Theorem. Finally we prove the Dominated Convergence Theorem (using both the Monotone Convergence Theorem and the Bounded Convergence Theorem). There …

2. Convergence theorems In this section we analyze the dynamics of integrabilty in the case when se-quences of measurable functions are considered. Roughly speaking, a “convergence theorem” states that integrability is preserved under taking limits. In other words, if one has a sequence (f n)∞ =1 of integrable functions, and if f is some kind of a limit of the f n’s, then we would like
