Talk:Double number

The [Dec 2007 issue of the AMS Notices] has an article by Vladimir V. Kisil which clearly states that Double numbers have $$i^2=1$$ (which are discussed in the article split-complex number) and Dual numbers have $$i^2=0$$ (which are discussed in the article on Dual numbers. Evidently the research community has significant ambiguity in the naming of Dual and Double numbers.  I think the recent AMS article should advise until the clarity in the history and logic content of the split-complex number and dual number articles lead to a consensus naming convention (and presumably a clear explanation for the historical ambiguity).
