Unimportant neologism?

This term and its minor variations get the total of 3+1 hits on MathSciNet. While possibly a natural generalization of convex polyhedra, I don't see any substantial evidence that they have been studied, at least under this name. Arcfrk (talk) 21:01, 17 April 2010 (UTC)[reply]

Being unfamiliar with the term myself, I challenged it on Nbarth's talk page. I have since confirmed that reference may indeed be found in McMullen and Schulte, as stated. An accepted term for this class of polytope is long overdue. To students of elementary geometry and projective geometry this is an important class. Previous studies tended to refer to examples as "hemi" figures (such as the hemicube), but as the subject has developed over the last few decades that terminology has become stretched to the point of inappropriateness. I am willing to bet thet you would find plenty of "hemi" references on MathSciNet. Whether McMullen and Schulte have adopted a neologism or not is immaterial - they lend it full mathematical authority and it is worthy of encyclopedic treatment. I am delighted that such a sensible name has been provided at last. -- Cheers, Steelpillow (Talk) 14:03, 18 April 2010 (UTC)[reply]
