Nachsorge früh verwaister Eltern that are invariant under a permutation of their variables, and some whose associated Newton polytope is of a special type. For polynomials with special structure, we discuss conditions which imply or characterize when the polynomial is psd, and when it is sos.

Appetitlosigkeit und MangelernährungA sum of squares (sos) representation for . is a global certificate of positivity, by which we mean an immediate proof that . is positive semidefinite (psd). In this chapter, we discuss finding and counting sos representations for a given ..
