[sage-combinat-devel] Re: Do we want to have the category of associative magmas?

2013-05-02 Thread Simon King
Hi all, I hope I summarise the discussion correctly: - There is no mathematical difference between a quiver and a digraph. Hence, there will be no separate sub-class Quiver of DiGraph. - How shall we call the algebraic structure formed by the paths in a quiver? PathMonoid? PathMagma?

Hi William, This sounds indeed like an interesting idea! As far as I know, the combinatorics tutorial that you mention has already appeared in a French Sage book, see http://sagebook.gforge.inria.fr/ . But I am sure Nicolas can comment on this. Perhaps the entire French book could be translated
