Jump loci for the rank of matrices and Betti numbers of chain complexes over Laurent polynomial rings

Thomas Huettemann, Zuhong Zhang

Let $K$ be a non-empty set of ideals of the commutative ring $R$ , closed under taking smaller ideals. A subset $X$ of the group ring $R [Z^{s}]$ is called a $K$ -set if the id…

Annihilators in $N^{k}$ -graded and $Z^{k}$ -graded rings

Thomas Huettemann

It has been shown by McCoy that a right ideal of a polynomial ring with several indeterminates has a non-trivial homogeneous right annihilator of degree 0 provided its right annihi…
