Special regular polynomial skew products

Yugang Zhang

We define a regular polynomial skew product $(p (z), q (z, w))$ of $C^{2}$ of degree $d \geq 2$ to be special if it is triangularly conjugate to a map of the form $(p (z), q (w))$ ,…

Uniform bound on common periodic points for families of regular plane polynomial automorphisms

Marc Abboud, Yugang Zhang

Given two one-dimensional families $f$ and $g$ of regular plane polynomial automorphisms parameterised by an algebraic curve $B$ , all defined over some number field $K$ , such that…

Marked points of families of hyperbolic automorphisms of smooth complex projective varieties

Yugang Zhang

Let $I ¨ : X \to I^$ be a flat family of smooth complex projective varieties parameterized by a smooth quasi-projective variety $I^$ , and let $f : X \to X$ be a family of automorphisms…
