Newton polygons and Böttcher coordinates near infinity for polynomial skew products

Kohei Ueno

Let $f (z, w) = (p (z), q (z, w))$ be a polynomial skew product such that the degrees of $p$ and $q$ are grater than or equal to $2$ . Under one or two conditions, we prove that $f$ is conj…

Attraction rates for iterates of a superattracting skew product

Kohei Ueno

Let $f (z, w) = (p (z), q (z, w))$ be a holomorphic skew product with a superattracting fixed point at the origin. In the previous paper we have succeeded to specify a dominant term of $q$ …
