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 canonical height functions) for f and f^{-1}. Next we introduce for f the notion of good reduction at v, and using this notion, we show that the sum of v-adic Green functions over all v gives rise to a canonical height function for f that satisfies the Northcott-type finiteness property. Using previous… 

Examples of dynamical degree equals arithmetic degree

Let f : X --> X be a dominant rational map of a projective variety defined over a number field. An important geometric-dynamical invariant of f is its (first) dynamical degree d_f= lim

Abstract Let φ:ℙN⤏ℙN be a dominant rational map. The dynamical degree of φ is the quantity δφ=lim (deg φn)1/n. When φ is defined over ${\bar {{\mathbb {Q}}}}$, we define the arithmetic degree of a

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

Regular polynomial automorphisms in the space of planar quadratic rational maps

In this paper, we describe the semistable quotient of the set of regular polynomial automorphisms $${\mathcal {H}}_2^2$$ in the semistable locus of the moduli space of quadratic rational maps, using

Heights and periodic points for one-parameter families of Hénon maps

In this paper we study arithmetic properties of a one-parameter family ${\mathbf H}$ of Henon maps over the affine line. Given a family of initial points ${\mathbf P}$ satisfying a natural condition,

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

Ample canonical heights for endomorphisms on projective varieties

We define an "ample canonical height" for an endomorphism on a projective variety, which is essentially a generalization of the canonical heights for polarized endomorphisms introduced by

Canonical heights for plane polynomial maps of small topological degree

We study canonical heights for plane polynomial mappings of small topological degree. In particular, we prove that for points of canonical height zero, the arithmetic degree is bounded by the

The equidistribution of small points for strongly regular pairs of polynomial maps

In this paper, we prove the equidistribution of periodic points of a regular polynomial automorphism $$f : \mathbb{A }^n \rightarrow \mathbb{A }^n$$ defined over a number field $$K$$: let $$f$$ be a

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]

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
