Mating, paper folding, and an endomorphism of $$\mathbb {PC}^2$$. (English) Zbl 1408.37082
Summary: We are studying topological properties of the Julia set of the map $$F(z, p)=\left(\left(\frac{2z}{p+1}-1\right)^2,\left(\frac{p-1}{p+1}\right)^2\right)$$ of the complex projective plane $$\mathbb{PC}^2$$ to itself. We show a relation between this rational function and an uncountable family of “paper folding” plane filling curves.
