Theorem stoweidlem49 44755

Description: There exists a function q_n as in the proof of Lemma 1 in [BrosowskiDeutsh] p. 91 (at the top of page 91): 0 <= q_n <= 1 , q_n < ε on 𝑇 ∖ 𝑈, and q_n > 1 - ε on 𝑉. Here y is used to represent the final q_n in the paper (the one with n large enough), 𝑁 represents 𝑛 in the paper, 𝐾 represents 𝑘, 𝐷 represents δ, 𝐸 represents ε, and 𝑃 represents 𝑝. (Contributed by Glauco Siliprandi, 20-Apr-2017.)
