Code and files for: Unique powers-of-forms decompositions from simple Gram spectrahedra

This repository accompanies the paper Unique powers-of-forms decompositions from simple Gram spectrahedra. It contains: a tentative implementation of Algorithm 1 therein for powers-of-forms decomposition, including subroutines to: verify whether a form is uniquely Sum-of-Squares representable. compute the Sum-of-Squares support of a given SOS form. decompose positively weighted power sums of linear forms. data from the numerical experiments of Section 4.2.
