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 gen

Module theory is a fundamental area of algebra, taught in most universities at the graduate level. This textbook, written by two experienced teachers and researchers in the area, is based on courses given in their respective universities over the las

The concept of generalized path algebras was introduced in (Coelho, Liu, 2000). Roughly speaking, these algebras are constructed in a similar way to that of the path algebras over a quiver, the difference being that we assign an algebra to each verte

Let R be the pullback of two surjective homomorphisms of algebras A → B and C → B. Here we consider a particular class, the so-called linearly oriented pullback, where the injective and projective R-modules can be determined by those ones over A

As in Chapter I, we let k be an arbitrary (commutative) field. Our algebras are finite dimensional k-algebras, associative and with an identity. The main working tool in this book is the notion of almost split sequences. It arose from an attempt to u

The previous chapter was mainly of a theoretical nature: we defined irreducible morphisms and almost split sequences and started to explore their use for the understanding of the radical of a module category. However, we did not say much about the ex

In this book, we assume that the reader has some familiarity with the classical theory of algebras and modules, category theory and homological algebra, such as can be gained from most textbooks in these areas. The first section of this chapter is de
