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.

Finiteness of cominuscule quantum K-theory [PDF]
, 2010 The product of two Schubert classes in the quantum K-theory ring of a homogeneous space X = G/P is a formal power series with coefficients in the Grothendieck ring of algebraic vector bundles on X. We show that if X is cominuscule, then this power series

Stable intersections of tropical varieties [PDF]
, 2013 We give several characterizations of stable intersections of tropical cycles and establish their fundamental properties. We prove that the stable intersection of two tropical varieties is the tropicalization of the intersection of the classical varieties

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 ]
