On Generalized Uniserial Rings and Decompositions that Complement Direct Summands.
Generalized Uniserial Rings and their Kupisch Series.
A class of quasitilted rings that are not tilted
Based on the work of D. Happel, I. Reiten and S. Smalø on quasitilted artin algebras, the first two authors recently introduced the notion of quasitilted rings. Various authors have presented examples of quasitilted artin algebras that are not tilted. Here we present a class of right quasitilted rings that not right tilted, and we show that they satisfy a condition that would force a quasitilted artin algebra to be tilted.
