Extreme Points of Gram Spectrahedra of Binary Forms

The Gram spectrahedron Gram ( f ) of a form f with real coefficients is a compact affine-linear section of the cone of psd symmetric matrices. It parametrizes the sum of squares decompositions of  f , modulo orthogonal equivalence. For f a sufficiently general positive binary form of arbitrary degre...
