Let { f n } be a sequence of measurable functions, f n → f μ -a.e. on a measurable set E, μ ( E) < ∞. Let ϵ > 0 be given. Then ∀ n ∈ N ∃ A n ⊂ E with μ ( A n) < ϵ 2 n and ∃ N n such that ∀ x ∉ A n and k ≥ N n f k ( x) − f ( x) < ϵ. That is: if we define A = ∪ n = 1 ∞ A n with μ ...

Web叶果洛夫定理（及其逆定理）说明了勒贝格框架的完备性，即在合理的测度理论的基础上，点点收敛和一致收敛的区别并不重要，逻辑上的差别不会影响积分理论的完备性。. 叶果洛夫定理说，在测度有限集上，点点收敛蕴含 近一致收敛 （或称 几乎一致收敛 ... Web比如Egoroff定理和Lusin定理的引理，单调收敛定理的引理，甚至有界收敛定理本身（它是控制函数为常函数的特殊情况）。 再比如高等代数里整个『极大线性无关组』及其相关的所有东西都只是脚手架而已，重要的只有『基和维数』。 WebDec 24, 2024 · 书中不仅包含数学定理和定义，而且还提出了富有启发性的问题，以便读者更深入地理解书中内容。 与上一版相比，第4版的主要更新如下： 新增了50%的习题。 证明了一些基本结果，包括Egoroff定理和Urysohn引理。 buy health affiliate
