Resumen:
The aim of this article is to give a method to construct bimodule resolutionsof associative algebras, generalizing Bardzell´s well-known resolution of monomial algebras.We stress that this method leads to concrete computations, providing thus a useful tool forcomputing invariants associated to the considered algebras. We illustrate how to use it bygiving several examples in the last section of the article. In particular we give necessary andsucient conditions for noetherian down-up algebras to be 3-Calabi-Yau.
