Modules with Krull Dimension of at Most α


Department of Mathematics, Shahid Chamran University, Ahvaz, Iran


In this article we have introduced and studied the notation of  α-loewy modules (0-loewy modules is just a loewy module). Using this concept we extend some of the basic results of loewy modules to α-loewy modules and we find a universal upper bound for Krull dimension over ߙ- loewy rings. In particular, we show that module M has Krull dimension α if and only if each factor module of M is lambda-loewy modules for some  lambda <=α  and has finite Goldie dimension.
