A lower bound for polynomial volume growth of automorphisms of zero entropy

Fei Hu, Chen Jiang

Let $X$ be a normal projective variety of dimension $d$ , and let $f$ be a zero-entropy automorphism of $X$ . Denote by $k$ the first-degree growth rate of $f$ , so that $°_1(f^n) \as…

An upper bound for polynomial volume growth of automorphisms of zero entropy

Fei Hu, Chen Jiang

Let $X$ be a normal projective variety of dimension $d$ over an algebraically closed field and $f$ an automorphism of $X$ . Suppose that the pullback $f^*|_{\mathsf{N}^1(X)_\mathbf{…
