Superroots (formal powerseries)

[bo198214]

I've uploaded that "WexZal"-article; it is originally in plain text (around 1998, if I recall right) but I thought it might be better to have it in .pdf. In a private mail the author welcomed to distribute this text. I'll add that statement later (I'll put it into Henryk's lib, too)

Thanks a lot Gottfried!
Why is this not published as a proper book?
I think there should be included some more data,
like finishing date and some jacket text about the authors.

And great: it contains appliations, as this really often asked and some ignorant physicists just think that there can not be applications.
