Purity of polynomial modules and inverse polynomial modules

Sangwon Park and Eunha Cho

Dong-A University, Dong-A University

Abstract

In this paper we show that we can extend the purity of left $R$-modules to the case of polynomial modules, bipolynomial modules, and also inverse polynomial modules.

Keywords: module, pure, pure submodule, inverse polynomial module
