Abstract

We consider filtered or graded algebras AA over a field KK. Assume that there is a discrete valuation OvO_v of KK with mvm_v its maximal ideal and kv:=Ov/mvk_v:=O_v/m_v its residue field. Let Λ\Lambda be OvO_v-order such that ΛK=A\Lambda K=A and Λˉ:=kvOvΛ\bar{\Lambda}:=k_v\otimes_{O_v}\Lambda the Λ\Lambda-reduction of AA at the place KkvK\leadsto k_v. Using the filtration of AA induced by Λ\Lambda we shall prove that for certain algebras AA their properties are related to Λˉ\bar{\Lambda}.
