Primary Decomposition And Secondary Representation Of Modules Over A Commutative Ring, Muslim Baig Apr 2009

Primary Decomposition And Secondary Representation Of Modules Over A Commutative Ring, Muslim Baig

Mathematics Theses

This paper presents the theory of Secondary Representation of modules over a commutative ring and their Attached Primes; introduced in 1973 by I. MacDonald as a dual to the important theory of associated primes and primary decomposition in commutative algebra. The paper explores many of the basic aspects of the theory of primary decomposition and associated primes of modules in the hopes to delineate and motivate the construction of a secondary representation, when possible. The thesis discusses the results of the uniqueness of representable modules and their attached primes, and, in particular, the existence of a secondary representation for Artinian …
