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)
