High Angle of Attack Aerodynamicsnot have a similar theory for studying representation-infinite algebras, but the ideas and techniques developed for representation-finite algebras still show their usefulness when applied to the understanding of new classes. The aim of this chapter is to prove some of the most important known result

https://doi.org/10.1007/978-1-4612-2824-0ain working tool in this book is the notion of almost split sequences. It arose from an attempt to understand the morphisms lying in the radical of a module category. From this attempt, Auslander and Reiten extracted the notions of irreducible morphisms and almost split sequences, which allow all ir

High Angle of Attack Aerodynamics algebra of some “well-chosen” module. For instance, the classical Morita theorem asserts that, given a progenerator . of the module category of an algebra ., that is, a projective module . that is also a generator of ., the categories . and . are equivalent. This implies that, from the point of vie

High Angle of Attack Aerodynamicss representation-finite or not, and, if this was the case, of computing all its (isoclasses of) indecomposable modules. Indeed, it was believed that this class of algebras would be relatively easy to classify and that their indecomposable modules have a relatively simple structure. This approach was
