Abstract: On a closed even conformal manifold $ (M,c)$, such that the critical GJMS operator has a non-trivial kernel, we identify and discuss the role of a finite dimensional vector space $ \mathcal{N}(\mathcal{Q})$ of functions determined by the conformal structure. Using these we describe an infinite dimensional class of functions that cannot be the Q-curvature $ Q^g$ for any $ g\in c$. If certain functions arise in $ \mathcal N(\mathcal Q)$, then $ Q^g$ cannot be constant for any $ g\in c$.
