On the correspondence between path algebras and generalized path algebras (2112.12189v1)

Abstract: The concept of generalized path algebras was introduced in (Coelho and Liu, 2000). It was shown in (Ib\'a~nez Cobos et al., 2008) how to obtain the Gabriel quiver of a given generalized path algebra. In this article, we generalize the concept of generalized path algebra to allow them to have relations, and we extend the result in (Ib\'a~nez Cobos et al., 2008) to this new setting. Moreover, we use the extended result mentioned above to address the inverse problem: that is, the problem of determining when a given algebra is isomorphic to a generalized path algebra in a non-trivial way.
