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)

Proposed deletion of Colinear map

The article Colinear map has been proposed for deletion because of the following concern:

While all constructive contributions to Wikipedia are appreciated, pages may be deleted for any of several reasons.

You may prevent the proposed deletion by removing the {{proposed deletion/dated}} notice, but please explain why in your edit summary or on the article's talk page.

Please consider improving the page to address the issues raised. Removing {{proposed deletion/dated}} will stop the proposed deletion process, but other deletion processes exist. In particular, the speedy deletion process can result in deletion without discussion, and articles for deletion allows discussion to reach consensus for deletion.
