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 …

M Adamaszek, H Adams, S Reddy - Journal of Topology and …, 2019 - World Scientific
For X a metric space and r> 0 a scale parameter, the Vietoris–Rips simplicial complex
VR<(X; r)(resp. VR≤(X; r)) has X as its vertex set, and a finite subset σ⊆ X as a simplex …

Castelnuovo-Mumford regularity of unprojections and the Eisenbud-Goto regularity conjecture

J Choe - arXiv preprint arXiv:2206.06151, 2022 - arxiv.org
McCullough and Peeva found counterexamples to the Eisenbud-Goto conjecture on the
Castelnuovo-Mumford regularity by using Rees-like algebras. In this paper, we suggest …

Cubics in 10 variables vs. cubics in 1000 variables: uniformity phenomena for bounded degree polynomials

D Erman, S Sam, A Snowden - Bulletin of the American Mathematical …, 2019 - ams.org
Hilbert famously showed that polynomials in $ n $ variables are not too complicated, in
various senses. For example, the Hilbert Syzygy Theorem shows that the process of …

From a local ring to its associated graded algebra

A De Stefani, ME Rossi, M Varbaro - arXiv preprint arXiv:2406.16421, 2024 - arxiv.org
Let $(R,\mathfrak {m}) $ be a complete local ring, and $ G={\rm gr} _ {\mathfrak {m}}(R) $ be
its associated graded ring. We introduce a homogenization technique which allows to relate …
