Talk:Star product

this page should also mention the Groenewold Moyal product (often called a star product) and the more general Gutt product
 * There's already an article on the Moyal product. But feel free to add a link to it from here if it is sometimes called a star product. Michael Slone (talk) 16:04, 18 May 2006 (UTC)

Alas! (I believe) this is one of the least fortunate synonymies in mathematics and physics. The Groenewold product, also all but universally mis-quoted as "Moyal product", and wiki-linked as such, is also called "star product", but hardly connects to this one here, in any useful way. So, I'd let things lie as they are now: avoid any contact of this star product with the operator star product introduced by Groenewold, and misnamed after Moyal, and expect the reader to seek it by its common rubric Moyal product. Admittedly a strange compromise, but at least it prevents further confusion. Cuzkatzimhut (talk) 14:54, 23 May 2009 (UTC)
