On the dimension of the strongly robust complex for configurations in general position

Dimitra Kosta, Apostolos Thoma, Marius Vladoiu

Strongly robust toric ideals are the toric ideals for which the set of indispensable binomials is the Graver basis. The strongly robust simplicial complex $Δ_{T}$ of a simple toric i…

Radical splittings of toric ideals

Anargyros Katsabekis, Apostolos Thoma

Let $I_{A} \subset K [x_{1}, \dots, x_{n}]$ be a toric ideal. In this paper, we provide a necessary and sufficient condition for the toric variety $V (I_{A})$ , over an algebraically closed fi…

Toric splittings

Anargyros Katsabekis, Apostolos Thoma

The toric ideal $I_{A}$ is splittable if it has a toric splitting; namely, if there exist toric ideals $I_{A_{1}}, I_{A_{2}}$ such that $I_{A} = I_{A_{1}} + I_{A_{2}}$ and $I_{A_{i}} \neq = I_{A}$ for…

Splittings of toric ideals of graphs

Anargyros Katsabekis, Apostolos Thoma

Let $G$ be a simple graph on the vertex set ${v_{1}, \dots, v_{n}}$ . An algebraic object attached to $G$ is the toric ideal $I_{G}$ . We say that $I_{G}$ is subgraph splittable if ther…

Self-dual toric varieties

Apostolos Thoma, Marius Vladoiu

We describe explicitly all multisets of weights whose defining projective toric varieties are self-dual. In addition, we describe a remarkable and unexpected combinatorial behaviou…

The strongly robust simplicial complex of monomial curves

Dimitra Kosta, Apostolos Thoma, Marius Vladoiu

To every simple toric ideal $I_{T}$ one can associate the strongly robust simplicial complex $Δ_{T}$ , which determines the strongly robust property for all ideals that have $I_{T}$ as th…
