In the paper "Uniformity of Mordell-Lang" by Vesselin Dimitrov, Philipp Habegger and Ziyang Gao ([DGH21], they use Silverman's Height Inequality and they give a proof of the same which makes use of Cartier divisors and hence drops the flatness assumption of structure morphisms of compactified abelian schemes. However, their proof makes use of Hironaka's theorem on resolution of singularities which is unknown for fields of positive characteristic. We try to slightly modify their ideas, use blow-ups in place of Hironaka's theorem to make the proof effective for any fields with product formula where heights can be defined and any normal quasi.projective variety as a base. We work in the more general set-up of dynamical systems. As an application we prove certain variants of the specialisation theorems in [Sil83] with restricted hypotheses in higher dimensional bases.
