| Description: Create an atom under a hyperplane. Part of proof of Lemma B in [Crawley] p. 112. (lhpat 40536 analog.) TODO: This changes 𝑈𝐶𝑉 in l1cvpat 39547 and l1cvat 39548 to 𝑈 ∈ 𝐻, which in turn change 𝑈 ∈ 𝐻 in islshpcv 39546 to 𝑈𝐶𝑉, with a couple of conversions of span to atom. Seems convoluted. Would a direct proof be better? (Contributed by NM, 11-Jan-2015.) |
