Counterexamples to the Eisenbud–Goto regularity conjecture

J McCullough, I Peeva - Journal of the American Mathematical Society, 2018 - ams.org
Our main theorem shows that the regularity of nondegenerate homogeneous prime ideals is
not bounded by any polynomial function of the degree; this holds over any field $ k $. In …

A finite classification of (xy)-primary ideals of low multiplicity

P Mantero, J McCullough - Collectanea Mathematica, 2018 - Springer
Let S be a polynomial ring over an algebraically closed field k. Let x and y denote linearly
independent linear forms in S so that p=(x, y) p=(x, y) is a height two prime ideal. This paper …

Towards Boij–Söderberg theory for Grassmannians: the case of square matrices

N Ford, J Levinson, S Sam - Algebra & Number Theory, 2018 - msp.org
We characterize the cone of GL-equivariant Betti tables of Cohen–Macaulay modules of
codimension 1, up to rational multiple, over the coordinate ring of square matrices. This …

Free resolutions of tangent cones of complete intersection monomial curves
