Nov 19, 2017 at 21:05	comment	added	Hector Blandin		Is $p_{1}^{k}$ the example of a homogeneous symmetric polynomial that is not an $n$-exception. I believe is the only one where the dimension of the real span of $A_f$ is exactly 1. For any other homogeneous symmetric polynomial this dimension is always $n$ or $n-1$.
