The general structure of inverse polynomial modules

Sangwon Park (2001)

Czechoslovak Mathematical Journal


In this paper we compute injective, projective and flat dimensions of inverse polynomial modules as R [ x ] -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.

Adic-completion and some dual homological results.

Anne-Marie Simon (1992)

Publicacions Matemàtiques


Let a be an ideal of a commutative ring A. There is a kind of duality between the left derived functors Ui a of the a-adic completion functor, called local homology functors, and the local cohomology functors Ha i. Some dual results are obtained for these Ui a, and also inequalities involving both local homology...
