On Difference-of-SOS and Difference-of-Convex-SOS Decompositions for Polynomials

Yi-Shuai Niu, Hoai An Le Thi, Dinh Tao Pham

In this article, we are interested in developing polynomial decomposition techniques based on sums-of-squares (SOS), namely the difference-of-sums-of-squares (D-SOS) and the differ…
