Thank you Ralf, that is exactly what I was hoping for. Oddly I did "play" with the TaylorSeries domain even before the SparseMultivariant ... domain, using my local version of FriCAS instead of the wiki, but I could not get either of these to work properly. FriCAS reported most functions as unimplemented so I thought maybe these domains where somehow unfinished and incomplete. Perhaps there is something wrong with my local version? Or maybe it was because I was using 'TaylorSeries Integer' in a manner I thought analogous to 'Polynomial Integer', but really what I needed was 'TaylorSeries Fraction Integer'? Was that what you mean by your comment about Fraction Integer? I am travelling right now, but when I get back I will try this all again.
About the wiki: Email notification would be nice but setting it up would probably require that Waldek make some special arrangement with his university network support people to allow mail forwarding from the axiom-wiki virtual machine. In some universities this might require some very convincing argument because of fears of possible abuse. I did not change the content of the wiki page that you authored, but of course it is the nature of a wiki that one is expected to comment on web pages and to feel free to modify, add material and improve things the way one thinks best. A wiki is supposed to be collaborative. There is no such thing as "ownership" of a page but of course many people do often quite naturally feel most inclined only to change those things which they have personally authored. I hope you do not feel like I did so inappropriately. Bill.
