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 $Â°_1(f^n) \a…

Birational boundedness of rationally connected log Calabi-Yau pairs with fixed index

Jingjun Han, Chen Jiang

We show that the set of rationally connected projective varieties $X$ of a fixed dimension such that $(X, B)$ is klt, and $- l (K_{X} + B)$ is Cartier and nef for some fixed positive inte…
