[edit] Formal power series

Hi. I reverted your edit to formal power series because that section in the article does not assume that X is a complex variable or that the series is even convergent. Rather, X is a formal variable, and the series can have its coefficient in any ring, and complex analysis is not applicable except in a very special case of holomorphic functions.

I wonder what you think. You can reply here. Thanks. Oleg Alexandrov (talk) 03:21, 20 February 2007 (UTC)

Hello Ivan. I'm curious where you got this wonderful piece of information? Never thought or heard of that before! Cheers.--K.C. Tang 03:55, 25 May 2007 (UTC)

O, the prescriptionists! Some people hold a grudge against them, but they often have some useful things to offer. Cheers.--K.C. Tang 04:58, 25 May 2007 (UTC)
