Projective Modules over Dedekind Domains
In these notes we will first define projective modules and prove some standard properties of those modules. Then we will classify finitely generated projective modules over Dedekind domains Remark 0.1. All rings will be commutative with 1. 1. Projective modules Definition 1.1. Let R be a ring and let M be an R-module. Then M is called projective if for all surjections p : N → N ′ and a map f : ...
متن کاملDrinfeld-hecke Algebras over Cocommutative Algebras
If A is a cocommutative algebra with coproduct, then so is the smash product algebra of a symmetric algebra SymV with A, where V is an A-module. Such smash product algebras, with A a group ring or a Lie algebra, have been deformed by Drinfel’d and more recently, Crawley-Boevey and Holland, Etingof and Ginzburg (and Gan), and others. These algebras include symplectic reflection algebras and infi...
متن کاملComputations in Modules over Commutative Domains
This paper is a review of results on computational methods of linear algebra over commutative domains. Methods for the following problems are examined: solution of systems of linear equations, computation of determinants, computation of adjoint and inverse matrices, computation of the characteristic polynomial of a matrix.
متن کاملPrimary Decomposition of Modules over Dedekind Domains Using Gröbner Bases
In [6] was proved that if R is a principal ideal domain and N ⊂ M are submodules of R[x1, . . . , xn], then the primary decomposition for N in M can be computed using Gröbner bases. In this paper we extend this result to Dedekind domains. The procedure that computed the primary decomposition is illustrated with an example.
متن کاملMinimal Prime Ideals of Ore Extensions over Commutative Dedekind Domains
Let R = D[x;σ, δ] be an Ore extension over a commutative Dedekind domain D, where σ is an automorphism on D. In the case δ = 0 Marubayashi et. al. already investigated the class of minimal prime ideals in term of their contraction on the coefficient ring D. In this note we extend this result to a general case δ 6= 0.
