Theorem cdleme7 34378
Description: Part of proof of Lemma E in [Crawley] p. 113. 𝐺 and 𝐹 represent fs(r) and f(s) respectively. 𝑊 is the fiducial co-atom (hyperplane) that they call w. Here and in cdleme7ga 34377 above, we show that fs(r) W (top of p. 114), meaning it is an atom and not under w, which in our notation is expressed as 𝐺𝐴 ∧ ¬ 𝐺 𝑊. (Note that we do not have a symbol for their W.) Their proof provides no details of our cdleme7aa 34371 through cdleme7 34378, so there may be a simpler proof that we have overlooked.
