Abstract

We present basic properties of Gr\"obner bases of submodules of a free module of finite rank over a polynomial ring RR with coefficients in a graded truncated discrete valuations ring AA. As an application, we give a criterion for a finitely generated RR-module to be flat over AA. Its non-graded version is also given.
