Given a ﬁnite simplicial graph G with a group (or monoid) attached to each vertex, the associated graph product is the group (monoid) gen-erated by each of the vertex groups (monoids) with the added relations that elements of distinct adjacent vertex groups commute. Graph products were deﬁned by Green [15], and have also been ...

WebThe graph product is an operator mixing direct and free products. Whether the product between two monoids is free or direct is determined by a simplicial graph, that is, a graph with no loops. Considering a monoid attached to each vertex of the graph, the associated graph product is the monoid generated by WebThe endomorphism monoids of graphs allow to establish a natural connection between graph theory and algebraic theory of semigroups.
