Quasihomogeneous isolated singularities in terms of syzygies and foliations

Hamid Hassanzadeh, Abbas Nasrollah Nejad, Aron Simis

One considers quasihomogeneous isolated singularities of hypersurfaces in arbitrary dimensions through the lenses of three apparently quite apart themes: syzygies, singularity inva…

Additions to a theorem of Morey-Ulrich

Thiago Fiel, Zaqueu Ramos, Aron Simis

Let $R = k [x_{1}, \dots, x_{d}]$ denote a standard graded polynomial ring over an algebraically closed field $k$ , and let $I \subset R$ be a perfect ideal of codimension $2$ with an $n…

Cohen--Macaulay ideals of codimension two and the geometry of plane points

Dayane Lira, Geisa Oliveira, Zaqueu Ramos +1

We consider classes of codimension two Cohen--Macaulay ideals over a standard graded polynomial ring over a field. We revisit Vasconcelos' problem on $3 \times 2$ matrices with homo…
