Silverman proved a height inequality for jointly regular family of rational maps and the author improved it for jointly regular pairs. In this paper, we provide the same improvement for jointly regular family; if S is a jointly regular set of rational maps, then \sum_{f\in S} \dfrac{1}{\deg f} h\bigl(f(P) \bigr) > (1+ \dfrac{1}{r}) f(P) - C where r = \max_{f\in S} r(f). 
Periodic points and arithmetic degrees of certain rational self-maps
. Consider a cohomologically hyperbolic birational self-map defined over the algebraic numbers, for example, a birational self-map in dimension two with the first dynamical degree greater than one, or

Maximal ratio of coefficients of divisors and an upper bound for height for rational maps
When we have a morphism f : P^n -> P^n, then we have an inequality \frac{1}{\deg f} h(f(P)) +C > h(P) which provides a good upper bound of $h(P)$. However, if $f$ is a rational map, then
Height Bounds and Preperiodic Points for Families of Jointly Regular Affine Maps
h ( φ(P ) ) = d · h(P ) + O(1) for all P ∈ P (K̄) combined with the fact that there are only finitely many K-rational points of bounded height leads immediately to a proof of Northcott’s Theorem [18]
Local and global canonical height functions for affine space regular automorphisms
Let f: A^N \to A^N be a regular polynomial automorphism defined over a number field K. For each place v of K, we construct the v-adic Green functions G_{f,v} and G_{f^{-1},v} (i.e., the v-adic
An upper bound for the height for regular affine automorphisms of A^n
In 2006, Kawaguchi proved a lower bound for height of h(f(P)) when f is a regular affine automorphism of A^2, and he conjectured that a similar estimate is also true for regular affine automorphisms
Canonical height functions for affine plane automorphisms
Let be a polynomial automorphism of dynamical degree δ≥2 over a number field K. We construct height functions defined on that transform well relative to f, which we call canonical height functions
