The dual notion of prime submodules
In this paper the concept of the second submodule (the dual notion of prime submodule) is introduced.
The first term in a minimal pure injective resolution.
The general structure of inverse polynomial modules
In this paper we compute injective, projective and flat dimensions of inverse polynomial modules as -modules. We also generalize Hom and Ext functors of inverse polynomial modules to any submonoid but we show Tor functor of inverse polynomial modules can be generalized only for a symmetric submonoid.
Two properties of the power series ring.
