Let be a dominant rational self-map of a smooth projective variety defined over $\overline{\mathbb{Q}}$ . For each point $P\in X(\overline{\mathbb{Q}})$ whose forward $f$ -orbit is well defined, Silverman introduced the arithmetic degree $\unicode[STIX]{x1D6FC}_{f}(P)$ , which measures the growth rate of the heights of the points $f^{n}(P)$ . Kawaguchi and Silverman conjectured that $\unicode[STIX]{x1D6FC}_{f}(P)$ is well defined and that, as $P$ varies, the set of values obtained by $\unicode… Expand

Current trends and open problems in arithmetic dynamics
Arithmetic dynamics is the study of number theoretic properties of dynamical systems. A relatively new field, it draws inspiration partly from dynamical analogues of theorems and conjectures inExpand

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 aExpand

We consider the family fa,b(x,y)=(y,(y+a)/(x+b)) of birational maps of the plane and the parameter values (a,b) for which fa,b gives an automorphism of a rational surface. In particular, we findExpand
