On the Noether bound for noncommutative rings [PDF]
Proceedings of the American Mathematical Society, 2019 We present two noncommutative algebras over a field of characteristic zero that each posses a family of actions by cyclic groups of order $2n$, represented in $n \times n$ matrices, requiring generators of degree $3n$.

Formalized linear algebra over Elementary Divisor Rings in Coq [PDF]
Log. Methods Comput. Sci., 2016 This paper presents a Coq formalization of linear algebra over elementary divisor rings, that is, rings where every matrix is equivalent to a matrix in Smith normal form.

Cluster algebras III: Upper bounds and double Bruhat cells [PDF]
, 2003 We continue the study of cluster algebras initiated in math.RT/0104151 and math.RA/0208229. We develop a new approach based on the notion of an upper cluster algebra, defined as an intersection of certain Laurent polynomial rings.

Castelnuovo–Mumford regularity in biprojective spaces [PDF]
, 2002 We define the concept of regularity for bigraded modules over a bigraded polynomial ring. In this setting we prove analogs of some of the classical results on m-regularity for graded modules over polynomial algebras.

A Giambelli formula for even orthogonal Grassmannians [PDF]
, 2011 Let X be an orthogonal Grassmannian parametrizing isotropic subspaces in an even dimensional vector space equipped with a nondegenerate symmetric form. We prove a Giambelli formula which expresses an arbitrary Schubert class in the singular and quantum ...

Conormal Geometry of Maximal Minors [PDF]
, 1997 Let A be a Noetherian local domain, N be a finitely generated torsion-free module, and M a proper submodule that is generically equal to N . Let A [ N ] be an arbitrary graded overdomain of A generated as an A -algebra by N placed in degree 1. Let A [ M ]
