Böttcher coordinates at superattracting fixed points of holomorphic skew products
2016
Conformal Geometry and Dynamics
Let f : (C 2 , 0) → (C 2 , 0) be a germ of holomorphic skew product with a superattracting fixed point at the origin. If it has a suitable weight, then we can construct a Böttcher coordinate which conjugates f to the associated monomial map. This Böttcher coordinate is defined on an invariant open set whose interior or boundary contains the origin.
