Theorem stoweidlem38 43469

Description: This lemma is used to prove the existence of a function p as in Lemma 1 of [BrosowskiDeutsh] p. 90: p is in the subalgebra, such that 0 <= p <= 1, p_(t₀) = 0, and p > 0 on T - U. Z is used for t₀, P is used for p, (𝐺‘𝑖) is used for p_(t_i). (Contributed by Glauco Siliprandi, 20-Apr-2017.)
