On the minimal free resolution of the universal ring for resolutions of length two

Andrew R. Kustin, Jerzy M. Weyman

Hochster established the existence of a commutative noetherian ring and a universal resolution of the form s…

On the number of subrepresentations of a general quiver representation

Harm Derksen, Aidan Schofield, Jerzy Weyman

It is well-known that the intersection multiplicities of Schubert classes in the Grassmanian are Littlewood-Richardson coefficients. We generalize this statement in the context of…

On Ideal Generators for Affine Schubert Varieties

V. Kreiman, V. Lakshmibai, P. Magyar +1

We consider a certain class of Schubert varieties of the affine Grassmannian of type A. By embedding a Schubert variety into a finite-dimensional Grassmannian, we construct an expl…

A Fitting Lemma for Z/2-graded modules

David Eisenbud, Jerzy Weyman

We study the annihilator of the cokernel of a map of free Z/2-graded modules over a Z/2-graded skew-commutative algebra in characteristic 0 and define analogues of its Fitting idea…

Two results on equations of nilpotent orbits

J. Weyman

We prove two results on the defining ideals of certain varieties of matrices. Let us fix two positive integers r, e. Let M(r) be the set of r x r matrices over a field K. We consid…

Graded characters of modules supported in the closure of a nilpotent conjugacy class

Mark Shimozono, Jerzy Weyman

We study the Poincare polynomials of isotypic components of a natural family of graded GL(n)-modules supported in the closure of a nilpotent conjugacy class. These polynomials gene…
