Geometry of varieties for graded maximal Cohen--Macaulay modules (2002.11294v2)

Published 26 Feb 2020 in math.AC and math.RT

Abstract: We study a variety for graded maximal Cohen--Macaulay modules, which was introduced by Dao and Shipman. The main result of this paper asserts that there are only a finite number of isomorphism classes of graded maximal Cohen--Macaulay modules with fixed Hilbert series over Cohen--Macaulay algebras of graded countable representation type.
