    Stable intersections of conformal cantor sets.
    (2021) Araújo, Hugo Fonseca; Moreira, Carlos Gustavo
    We investigate stable intersections of conformal Cantor sets and their consequences to dynamical systems. First we define this type of Cantor set and relate it to horseshoes appearing in automor- phisms of C2 . Then we study limit geometries, objects related to the asymptotic shape of the Cantor sets, to obtain a criterion that guarantees stable intersection between some configurations. Finally we show that the Buzzard construction of a Newhouse region on Aut(C2 ) can be seem as a case of stable intersection of Cantor sets in our sense and give some (not optimal) estimative on how “thick” those sets have to be.
