Sums of Squares and Varieties of Minimal Degree

The study of nonnegativity and its relation with sums of squares is a basic challenge in real algebraic geometry. The classification of varieties of minimal degree is one of the milestones of classical complex algebraic geometry. The goal of this paper is to establish the deep connection between these apparently separate topics. To achieve this, let X ⊆ P be an embedded real projective variety ...

Sums of Squares of Regular Functions on Real Algebraic Varieties

Let V be an affine algebraic variety over R (or any other real closed field R). We ask when it is true that every positive semidefinite (psd) polynomial function on V is a sum of squares (sos). We show that for dimV ≥ 3 the answer is always negative if V has a real point. Also, if V is a smooth non-rational curve all of whose points at infinity are real, the answer is again negative. The same h...

Germs of Integrable Forms and Varieties of Minimal Degree

We study the subvariety of integrable 1-forms in a finite dimensional vector space W ⊂ Ω(C, 0). We prove that the irreducible components with dimension comparable with the rank of W are of minimal degree.

On the Universal Gröbner Bases of Varieties of Minimal Degree

A universal Gröbner basis of an ideal is the union of all its reduced Gröbner bases. It is contained in the Graver basis, the set of all primitive elements. Obtaining an explicit description of either of these sets, or even a sharp degree bound for their elements, is a nontrivial task. In their ’95 paper, Graham, Diaconis and Sturmfels give a nice combinatorial description of the Graver basis f...
