Ideals of submaximal minors of sparse symmetric matrices

Jiahe Deng, Andreas Kretschmer

We study algebraic and homological properties of the ideal of submaximal minors of a sparse generic symmetric matrix. This ideal is generated by all $(n - 1)$ -minors of a symmetric $…

Thin polytopes: Lattice polytopes with vanishing local $h^{*}$ -polynomial

Christopher Borger, Andreas Kretschmer, Benjamin Nill

In this paper we study the novel notion of thin polytopes: lattice polytopes whose local $h^{*}$ -polynomials vanish. The local $h^{*}$ -polynomial is an important invariant in modern Eh…

The enumerative geometry of cubic hypersurfaces: point and line conditions

Mara Belotti, Alessandro Danelon, Claudia Fevola +1

In order to count the number of smooth cubic hypersurfaces tangent to a prescribed number of lines and passing through a given number of points, we construct a compactification of…
