| contents | Gotzmann's persistence theorem provides a method for determining the Hilbert polynomial of a subscheme of projective space by evaluating the Hilbert function at only two points, irrespective of the dimension of the ambient space. In arXiv:2405.02275 we established an analogue of Gotzmann's persistence theorem for smooth projective toric varieties. We generalise our results to the setting of Mori dream spaces, whose associated Cox rings are also finitely generated. We also give an alternative, stronger, persistence result for points in products of projective spaces. |
