Abstract

Let R[X] be the real polynomial ring in n variables. Pólya's Theorem says that if a homogeneous polynomial pεR[X] is positive on the standard n-simplex δn, then for sufficiently large N all the coefficients of (X1+...+Xn)Np are positive. We give a complete characterization of forms, possibly with zeros on δn, for which there exists N so that all coefficients of (X1+...+Xn)Np have only nonnegative coefficients, along with a bound on the N needed.
