Deformations of Codimension 2 Toric Varieties
We prove Sturmfels’ conjecture that toric varieties of codimension two have no other flat deformations than those obtained by Gröbner basis theory.
متن کاملOn Simplicial Toric Varieties of Codimension 2
We describe classes of toric varieties of codimension 2 which are either minimally defined by codim V +1 binomial equations over any algebraically closed field, or set-theoretic complete intersections in exactly one positive characteristic .
متن کاملSyzygies of Codimension 2 Lattice Ideals
The study of semigroup algebras has a long tradition in commutative algebra. Presentation ideals of semigroup algebras are called toric ideals, in reference to their prominent role in geometry. In this paper we consider the more general class of lattice ideals. Fix a polynomial ring S = k[x1, . . . , xn] over a field k and identify monomials x in S with vectors a ∈ N. Let L be any sublattice of...
