چکیده
|
In this work we present a systematic study of n-layered modules which are closely related to σ-modules. for each integer n ≥ 1 we prove some results for n-layered modules concerning when σ-modules are direct sum of countably generated modules. moreover, we discover additional restriction which leads to coinciding of n-layered modules and m-layered modules for n > m.
