On the generalized Scarf complex of lattice ideals

Hara Charalambous, Apostolos Thoma

Let $k$ be a field, $L \subset Z^{n}$ be a lattice such that $Ł \cap N^{n} = {0}$ , and $I_{Ł} \subset k [x_{1}, ..., x_{n}]$ the corresponding lattice ideal…

Complete Intersection Lattice Ideals

Marcel Morales, Apostolos Thoma

In this paper we completely characterize lattice ideals that are complete intersections or equivalently complete intersections finitely generated semigroups of $\bz^n\oplus T$ with…

Projections of cones and the arithmetical rank of toric varieties

Anargyros Katsabekis

Let $I_{M}$ and $I_{N}$ be defining ideals of toric varieties such that $I_{M}$ is a projection of $I_{N}$ , i.e. $I_{N} \subseteq I_{M}$ . We give necessary and sufficient conditions for the eq…

Stanley-Reisner rings and the radicals of lattice ideals

Anargyros Katsabekis, Marcel Morales, Apostolos Thoma

In this article we associate to every lattice ideal $I_{L, ρ} \subset K [x_{1}, ..., x_{m}]$ a cone $σ$ and a graph $G_{σ}$ with vertices the minimal generators of the Stanley-Reisner ideal…
