Minors of symmetric and exterior powers
Winfried Bruns, Wolmer V. Vasconcelos
We describe some of the determinantal ideals attached to symmetric, exterior and tensor powers of a matrix. The methods employed use elements of Zariski's theory of complete ideals…
Unimodular covers of multiples of polytopes
Winfried Bruns, Joseph Gubeladze
Let P be a d-dimensional lattice polytope. We show that there exists a natural number c_d, only depending on d, such that the multiples cP have a unimodular cover for every natural…
Higher polyhedral K-groups
Winfried Bruns, Joseph Gubeladze
We define higher polyhedral K-groups for commutative rings, starting from the stable groups of elementary automorphisms of polyhedral algebras. Both Volodin's theory and Quillen's…
Polyhedral K_2
Winfried Bruns, Joseph Gubeladze
Using elementary graded automorphisms of polytopal algebras (essentially the coordinate rings of projective toric varieties) polyhedral versions of the group of elementary matrices…
Algebras of minors
Winfried Bruns, Aldo Conca
Let be an matrix of indeterminates over a field (of sufficiently large characteristic) and the set of -minors of . We consider two objects: (1) the…
Problems and algorithms for affine semigroups
Winfried Bruns, Joseph Gubeladze, Ngo Viet Trung
In this article we overview those aspects of the theory of affine semigroups and their algebras that have been relevant for our own research, and pose several open problems. Answer…
