Deletion of Generalized quaternion interpolation

Comment: I found the (single) reference online: https://hal.archives-ouvertes.fr/inria-00073318/document. The whole thing looks borderline  and complete gibberish. I first tried to understand what this article is about without the reference with my smattering of elemental mathematics, and frankly the most basic things are not correctly explained. Some basic and probably incorrect summary of the reference follows with as little jargon as possible
