DOI: 10.1007/s10898-018-0706-2
Abstract: In this paper, we study some fundamental geometrical properties related to the $${\mathcal {S}}$$S-procedure. Given a pair of quadratic functions (g, f), it asks when “$$g(x)=0 \Longrightarrow ~ f(x)\ge 0$$g(x)=0⟹f(x)≥0” can imply “($$\exists \lambda \in {\mathbb… read more here.
