• Resumen

  • To a commutative ring $K$, and a family of $K$-algebras indexed by the vertex set of a graph, we associate a $K$-algebra obtained by a mixture of coproduct and tensor product constructions. For this, and related constructions, we give exact sequences and deduce homological properties.
