On primary decomposition of modules

Abstract

Primary decomposition is a very important tool of commutative algebra and geometry. In this paper we generalized some of the existing algorithms of primary decomposition developed by Eisenbud et al. (cf. [EHV]) for free modules and also filled some gaps by providing proofs of important theorems(2.9, 2.12, 2.13) appeared in [EHV]. All these algorithms are programmed and implemented in {\sc Singular}.
