The spectrum of a category of maximal Cohen-Macaulay modules [PDF]

open access: yes
We introduce an analog of the Ziegler spectrum for maximal Cohen-Macaulay modules over a complete Cohen-Macaulay local ring. We define a topology on the space of isomorphism classes of indecomposable maximal Cohen-Macaulay modules and investigate the ...

Cohen-Macaulay modules on hypersurface singularities I

open access: yesInventiones Mathematicae, 1986
Let \(R=P/(f)\) be an analytic hypersurface ring. The author investigates first the relation between maximal Cohen-Macaulay modules (MCM) over R and over \(R_ 1=P_ 1/(f+y^ 2)\), where \(P_ 1=P\) (and \(P=k\), k algebraically closed and char(k)\(\neq 2)\).

COHEN–MACAULAY MODULES OVER SOME NON–REDUCED CURVE SINGULARITIES

open access: yes, 2016
. In this article, we study Cohen–Macaulay modules over non–reduced curve singularities. We prove that the rings kJx, y, zK/(xy, yq−z2) have tame Cohen–Macaulay representation type.

On Cohen–Macaulay modules over the Weyl algebra

open access: yesInternational Journal of Algebra and Computation
We investigate a definition of Cohen–Macaulay modules over the Weyl algebra D and give a sufficient condition for a GKZ A-hypergeometric D-module to be Cohen–Macaulay.

Linkage of Cohen–Macaulay modules over a Gorenstein ring [PDF]

open access: yes, 2000
Let R be a Gorenstein complete local ring. We say that finitely generated modules M and N are linked if HomR/λ̄R(M,R/λ̄R)≅ΩR/λ̄R1(N), where λ̄ is a regular sequence contained in both of the annihilators of M and N.
