Geometry of varieties for graded maximal Cohen--Macaulay modules

Naoya Hiramatsu

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.
