Talk:Monoid (category theory)

History monoid edit

From what I'm reading, the history monoid is the categorical product in the category of monoids. Although I want to put this notation into this article, I'm somewhat nervous doing so, as the statement is coming from a computer science book rather than a category theory book. I have not yet personally verified that it really does satisfy all the needed morphism properties; maybe after lunch .... linas 17:27, 22 April 2007 (UTC)Reply
