On Separation of level sets for a pair of quadratic functions

Huu-Quang Nguyen, Ya-Chi Chu, Ruey-Lin Sheu

Given a quadratic function $f (x) = x^{T} A x + 2 a^{T} x + a_{0},$ it is possible that its level set ${x \in R^{n} : f (x) = 0}$ has two connected components and thus can be separated by the le…
