Theorem itg2monolem1 26051

Description: Lemma for itg2mono 26054. We show that for any constant 𝑡 less than one, 𝑡 · ∫₁𝐻 is less than 𝑆, and so ∫₁𝐻 ≤ 𝑆, which is one half of the equality in itg2mono 26054. Consider the sequence 𝐴(𝑛) = {𝑥 ∣ 𝑡 · 𝐻 ≤ 𝐹(𝑛)}. This is an increasing sequence of measurable sets whose union is ℝ, and so 𝐻 ↾ 𝐴(𝑛) has an integral which equals ∫₁𝐻 in the limit, by itg1climres 26015. Then by taking the limit in (𝑡 · 𝐻) ↾ 𝐴(𝑛) ≤ 𝐹(𝑛), we get 𝑡 · ∫₁𝐻 ≤ 𝑆 as desired. (Contributed by Mario Carneiro, 16-Aug-2014.) (Revised by Mario Carneiro, 23-Aug-2014.)
