:The [[vector space]] article already discusses [[module (mathematics)|module]]s in the section on generalizations. The link is somewhat out of place here. If there were an article on [[examples of modules]], it might be appropriate to link it from here (I'm not claiming such an article should exist). -- [[User:Fropuff|Fropuff]] 02:41, 12 January 2006 (UTC)
A vector space is a module over a division ring -- not over a field. This article errs because the set of quaternions is a division ring but not a field. To speak of a vector space over the quaternions you can't define vector spaces only over fields. [[User:Jalongi|Jalongi]] ([[User talk:Jalongi|talk]]) 07:11, 19 July 2009 (UTC)
