Arithmetical Rank of Toric Ideals Associated to Graphs
Let IG ⊂ K[x1, . . . , xm] be the toric ideal associated to a finite graph G. In this paper we study the binomial arithmetical rank and the Ghomogeneous arithmetical rank of IG in 2 cases: (1) G is bipartite, (2) IG is generated by quadratic binomials. In both cases we prove that the binomial arithmetical rank and the G-arithmetical rank coincide with the minimal number of generators of IG.

متن کاملToric Codes and Lattice Ideals
Let X be a complete simplicial toric variety over a finite field Fq with homogeneous coordinate ring S = Fq[x1, . . . , xr] and split torus TX ∼= (Fq). We prove that vanishing ideal of a subset Y of the torus TX is a lattice ideal if and only if Y is a subgroup. We show that these subgroups are exactly those subsets that are parameterized by Laurents monomials. We give an algorithm for determin...
متن کاملResidual Ideals of Maclane Valuations
Let K be a field equipped with a discrete valuation v. In a pioneering work, MacLane determined all valuations on K(x) extending v. His work was recently reviewed and generalized by Vaquié, by using the graded algebra of a valuation. We extend Vaquié’s approach by studying residual ideals of the graded algebra as an abstract counterpart of certain residual polynomials which play a key role in t...
متن کاملToric ideals, real toric varieties, and the moment map
This is a tutorial on some aspects of toric varieties related to their potential use in geometric modeling. We discuss projective toric varieties and their ideals, as well as real toric varieties and the moment map. In particular, we explain the relation between linear precision and the moment map.
