Talk:Ore extension

I found this page while browsing, and noticed a minor error: It was stated that an Ore extension was a normalizing extension. This is generally not true when delta is not equal to zero.

I also added a reference to the Goodearl-Wafield text, which has a detailed treatment of Ore extensions and is more up to date than McConnell-Robson or Rowen. ..Emanuel Acharon

Could we be a little more explicit than "a ring extension whose properties are well understood"? Thanks.--345Kai (talk) 10:59, 22 July 2011 (UTC)
