Varieties of tropical ideals are balanced

نویسندگان

چکیده

Tropical ideals, introduced in [12], define subschemes of tropical toric varieties. We prove that the top-dimensional parts their varieties are balanced polyhedral complexes same dimension as ideal. This means every subscheme a variety defined by ideal has an associated class Chow ring variety. A key tool proof is specialization variables yields another ideal; this plays role hyperplane sections theory. also show elimination theory (projection varieties) works for ideals classical case. The matroid condition defines crucial these results.

Tropical Varieties, Ideals and an Algebraic Nullstellensatz

The objective of this paper is to introduce the fundamental algebro-geometric constructions over the extended tropical semi-ring. The study of tropical varieties, co-varieties and ideals over this extension eventually yields the theorem of the weak tropical Nullstellensatz and gives an algebraic interpretation of the tropical Nullstellensatz.

Rough ideals based on ideal determined varieties

The paper is devoted to concern a relationship between rough set theory and universal algebra. Notions of lower and upper rough approximations on an algebraic structure induced by an ideal are introduced and some of their properties are studied. Also, notions of rough subalgebras and rough ideals with respect to an ideal of an algebraic structure, which is an extended notion of subalgebras and ...

On the Ideals of Secant Varieties of Segre Varieties

We establish basic techniques for studying the ideals of secant varieties of Segre varieties. We solve a conjecture of Garcia, Stillman and Sturmfels on the generators of the ideal of the first secant variety in the case of three factors and solve the conjecture set-theoretically for an arbitrary number of factors. We determine the low degree components of the ideals of secant varieties of smal...

Equations of Tropical Varieties

We introduce a scheme-theoretic enrichment of the principal objects of tropical geometry. Using a category of semiring schemes, we construct tropical hypersurfaces as schemes over idempotent semirings such as T = (R∪{−∞},max,+) by writing them as solution sets to explicit systems of tropical equations that are uniquely determined by tropical linear algebra. We then define a tropicalization func...

Ideals Defining Unions of Matrix Schubert Varieties

This note computes a Gröbner basis for the ideal defining a union of matrix Schubert varieties. Moreover, the theorem presented will work for any union of schemes defined by northwest rank conditions. This provides a means of intersecting a large class of determinantal ideals. Introduction We compute a Gröbner basis for the ideal defining a union of schemes defined by northwest rank conditions ...
