Theorem stoweidlem36 41863

Description: This lemma is used to prove the existence of a function p_t as in Lemma 1 of [BrosowskiDeutsh] p. 90 (at the beginning of Lemma 1): for all t in T - U, there exists a function p in the subalgebra, such that p_t ( t₀ ) = 0 , p_t ( t ) > 0, and 0 <= p_t <= 1. Z is used for t₀ , S is used for t e. T - U , h is used for p_t . G is used for (h_t)^2 and the final h is a normalized version of G ( divided by its norm, see the variable N ).
