Lei, Tan Matings of quadratic polynomials. (English) Zbl 0756.58024 Ergodic Theory Dyn. Syst. 12, No. 3, 589-620 (1992). We apply Thurston’s equivalence theory between dynamical systems of postcritically finite branched coverings and rational maps to try to construct, from a pair of polynomials, a rational map. We prove that given two postcritically finite quadratic polynomials \(f_ c: z\mapsto z^ 2+c\) and \(f_{c'}: z\mapsto z^ 2+c'\) one can get a rational map if and only if \(c\), \(c'\) are not in conjugate limbs of the Mandelbrot set.
