Talk:Quiver (mathematics)

From Wikipedia, the free encyclopedia

Multiplying paths together doesn't sound very well defined, unless Quivers carry a natural structure for multiplying them, which would make them almost identical to categories, except without identity elements.

The multiplication structure is perfectly natural -- it's concatenation. Observe that there are no commutativity restrictions, so quivers have quite a lot less structure than categories. Gleuschk 22:29, 27 September 2006 (UTC)

Well, so in order to avoid further misunderstandings, I'll just replace "composition" by concatenation. - Saibot2 10:44, 15 March 2007 (UTC)
