Spinor structures on free resolutions of codimension four Gorenstein ideals
arXiv:1912.07510
Abstract
We analyze the structure of spinor coordinates on resolutions of Gorenstein ideals of codimension four. As an application we produce a family of such ideals with seven generators which are not specializations of Kustin-Miller model.
