Resumo

The concept of generalized path algebras was introduced in Coelho and Liu (Lecture Notes in Pure and Appl. Math. 210, 53-66, 2000). Roughly speaking, these algebras are constructed in a way similar to that of path algebras over a quiver, the difference being that we assign an algebra to each vertex of the quiver and consider paths intercalated with elements from these algebras. Then we use concatenation of paths together with the algebra structure in each vertex to define multiplication. The representations of a generalized path algebra were described in Cobos et al. (Rev Roumaine Math Pures Appl 53(1):25-36, 2008), in terms of the representations of the algebras used in its construction. In this article, we continue our investigation started in Chust and Coelho (Comm Algebra 50(5):2056-2071, 2022) and extend the result mentioned above to describe the representations of the generalized bound path algebras, which are a quotient of a generalized path algebra by an ideal generated by relations. In particular, the representations associated with the projective and injective modules are described. (AU)
