Extreme Rays of the Hankel Spectrahedra for Ternary Forms

Grigoriy Blekherman, Rainer Sinn

Hankel spectrahedra are the dual convex cones to the cone of sums of squares of real polynomials, and we study them from the point of view of convex algebraic geometry. We show tha…

Algebraic Boundaries of Convex Semi-algebraic Sets

Rainer Sinn

We study the algebraic boundary of a convex semi-algebraic set via duality in convex and algebraic geometry. We generalize the correspondence of facets of a polytope to the vertice…
